As discussed above, the visual identification device 3, illustrated in
In some embodiment, the inserter is described in U.S. Patent Application Publication No. 2011/0077659, incorporated herein in its entirety. In some embodiment, the microelectronic chip 300 and a chip reading device 128 as illustrated in
The identification device 3 in some embodiments includes a robot assembly 42 that is driven by a controller, and an inserter 5 operatively associated with the robot assembly 42.
In one embodiment, the robotic assembly 42 described herein is meant to embrace any robotic configuration that allows positioning of the inserter 5, whereby actuation of the inserter 5 marks the substrate. In another embodiment, a robotic assembly positions the inserter 5 along a y-axis and an R axis. In a further embodiment, the robotic assembly 42 operates or controls operation of the inserter 5, for example, by actuating the inserter 5 to mark the marking substrate. In another embodiment, the robotic assembly 42 positions the inserter 5 along a Y-axis, a theta axis, and along an R axis.
The robotic assembly 42 (in combination with one or more actuators) may in some embodiments be configured to position a inserter 5 along any axis. For example, in one embodiment, the robotic assembly 42 can position the inserter 5 along a linear axes (e.g. Y and/or R), rotational axes (e.g. theta), or a combination thereof.
With the teachings provided herein, the skilled artisan can readily produce robot assemblies 42 that enable a inserter 5 to move about a desired axis. For example, in one embodiment, the inserter 5 moves about a linear axis by providing a linear track or can move about any other axis (e.g. rotational axis) by providing a track that follows the desired axis. As another example, in one embodiment, the inserter 5 moves about a rotational axis by providing a radial arm (e.g. an arm that extends from a pivot point). As another example, in one embodiment, the inserter 5 moves about a linear axis by providing a piston coupled to a crank pin. As another example, in one embodiment, the inserter 5 moves about a linear axis by providing a rack and pinion mechanism (where the marking device is attached to a linear rack portion). As another example, in one embodiment, the inserter 5 moves about a non-circular curved axis by providing a rack and pinion mechanism (where the marking device is attached to. the rack portion and the rack/pinion combination is configured therefore). As another example, in one embodiment, the inserter 5 moves about a rotational axis by providing a rack and pinion mechanism (where the marking device is attached to a circular pinion portion or where the marking device is attached to the rack portion and the rack portion is a circular shape). As another example, in one embodiment, the inserter 5 moves about a curved axis by providing a crank-slider mechanism (where the slider is a pivoting slider).
The robotic assembly 42 comprises at least a first actuator (also referred to herein as a ‘marking actuator’) that causes the identification device to deposit the microelectronic chip on the substrate, i.e. that ‘actuates for making a mark’, as used herein. The robotic assembly 42 in one embodiment, further comprises one or more additional actuators for positioning the robotic arm (and marking device) on or about the substrate prior to making a mark on the substrate and/or homing or otherwise disengaging the identification device thereafter.
In one embodiment, the actuator(s) are any type of actuator, for example, a motor, voice coil, screw, piezoelectric device, solenoid, or pneumatic pump. Useful motors include, for example, stepper motors and servo motors. In one embodiment, the actuator is a linear actuator (e.g. Y axis actuator), a rotational actuator (e.g. theta axis actuator), or an actuator that converts from rotational to linear motion or vice-versa (e.g. of the piston type). The actuator (e.g. marking actuator) can cause a robotic arm or identification device thereof to move in a constant motion or a reciprocating motion.
The actuator (e.g. motor) may in some embodiments be optionally controlled by a feedback mechanism, for example, a feedback mechanism that provides positional information of the robotic arm or identification device thereof. Optionally, a feedback mechanism is external to the actuator and comprises a flag fixed to a robotic arm or identification device and a sensor fixed in position with respect to a restraining device (or vice-versa). For example, one or more flags can be provided for each axis of movement such that the marking device can be properly positioned. Optionally, the robot assembly 42 comprises a “substrate” flag (or multiple substrate window flags) on a robotic arm (e.g. an arm actuated by a second actuator), wherein the substrate flag is positioned such that the flag detected by a sensor when the robotic arm has positioned identification device about the substrate (in position for marking) A marking actuator (first actuator) can then be actuated to make a mark (e.g. controlled by a servo motor coupled to an identification device by a reciprocating piston).
Optionally, a feedback mechanism is internal to the actuator. For example, in one embodiment a servo motor is used to provide an actuator (e.g. a first actuator). Generally, a servo motor includes a motor, a feedback device, and a drive. The motor operates on direct current, and is typically hotter and smaller than other motors producing a comparable amount of torque. The feedback device is often an encoder or resolver (e.g. 32 count encoder) mounted on the back of the motor, and the feedback device reports performance information such as motor position and motor speed back to the drive. The servo motor's drive provides current to the motor, and the drive can include a programmable control device (e.g., a controller) which dictates the current in response to the feedback from the feedback device. A servo motor can be controlled by an algorithm such as the proportional-integral-derivative (PID) algorithm. In one embodiment, a servo motor provides properties when used in an actuator (e.g. coupled to an identification device through a reciprocating piston such as a scotch yolk assembly).
Among other various properties taught herein, a servo motor can optionally be provided as a marking actuator to impart a marking system with the ability to stop the identification device's motion at a position that reduces the amount of motion needed by the robotic arm to change positions. For example, a identification device can be fixed to a piston which is coupled to servo motor for reciprocating up/down “marking” motion of the identification device, and the servo motor can be operated with such precision that the inserter can stop cyclical movement at top dead center (e.g. upon completion of a mark or a character thereof). This feature eliminates the possibility of dragging the identification device (e.g. inserter) on the marking surface without the use of global upward (or Z-axis) movement of the robotic arm itself (e.g. by a second actuator).
In one embodiment the actuator for marking a substrate actuates the identification device 3, and optionally, the robotic assembly 42 along one or more axes or around or about one or more points in space. Optional axes include linear axes and rotational axes, as depicted in
The skilled artisan will recognize that certain exemplary axes are defined relative to each other in robotic assemblies 42 of marking systems taught herein. For example, although certain descriptions and figures set forth the Z axis as the vertical axis, the skilled artisan will appreciate that this is done to illustrate the invention.
In one embodiment, an actuator actuates movement along a single axis. In another embodiment, an actuator actuates movement along a plurality of axes. Optionally, the identification device and/or robotic arm is capable of moving on plurality of axes, wherein movement along each of a plurality of axes is controlled be a different actuator.
Although the invention contemplates a marking system in which the identification device 3 and/or robotic assembly 42 is capable of moving on one, all, or less than all of the axes defined by
Useful robot assemblies 42 of the present invention can an actuator that causes a inserter 5 (of the identification device 3) to contact the substrate. Optionally, the actuator causes a marking member to pierce the substrate (e.g. to inject a tattoo). For example, the inserter can enter the skin and exit the skin along the same path, for example, by retracting from the skin, minimizing spread of the mark and tissue damage.
In one embodiment, the robotic assembly 42 comprises at least a first actuator that actuates the marking device for marking a mark (e.g. R or Z axis), and further comprises at least a second actuator (e.g. X, Y, Z, Phi, or theta axis) for positioning the robotic arm (and marking device). Optionally, the first actuator(s) is/are connected between the robotic arm and the marking device. This configuration allows more rapid placement of the identification device (i.e. position and angle Φ with respect to the body part to be marked) as illustrated in
In one embodiment, the robot assembly 42 comprises first and second actuators and the first actuator(s) actuates the marking device along the R or Z axis and the second actuator(s) actuates the marking device (and robotic arm) along the X, Y, Z, Phi, or theta axis. For example, the first actuator can actuate the marking device for making a mark along the R axis and the second device can actuator the marking device along the theta axis. Optionally, the first actuator comprises a servo motor (e.g. PID controlled) coupled to a piston (e.g. scotch yolk).
In one embodiment, the robot assembly 42 comprises first and second actuators and the first actuator(s) actuates the marking device along the X, Y, Z, or theta axis and the second actuator actuate(s) the marking device along the X, Y, Z, or theta axis.
In one embodiment, the robot assembly 42 comprises first, second, and third actuators and the first actuator(s) actuates the marking device along the R or Z axis, the second actuator(s) actuates the marking device (and robotic arm) along the X or theta axis, and the third actuator(s) actuates the marking device (and robotic arm) along the Y or Phi axis. Optionally, the first actuator comprises a servo motor (e.g. PID controlled) coupled to a piston (e.g. scotch yolk).
In some embodiments, as illustrated in
To transfer the microelectronic chip 300 into the dermis with less load force on the inserters and less discomfort to the animal may require the use of sharp inserter tips 220. Depending on the number of tattoos produced or chips inserted, inserters may need to be replaced periodically. Inserters may also require replacement in those cases where cross-contamination between animal populations must be prevented and inserter sharing is not permissible. In other instances, if inserters become damaged (e.g. the tips become bent), they need to be replaced. Regardless of the reason behind the need to change inserters, it is preferred that the design be such that the replacement is easily done by the user of the pigment tattooing system. Most noteworthy however is that it is desirable that in making a inserter change, minimum compromise be made in the repeatability of the inserter tip length deviation and inserter tip concentration deviation with respect to the marking device, particularly if no closed-loop feedback relative to the inserter tip penetration and lateral positioning into the dermal layer is provided.
In order to repeatably position the inserter 5 during inserter replacement, the identification device 3 may include a inserter cartridge 92 to which the inserter 5 may in some embodiments be accurately coupled. Turning now to
As illustrated in
To mount the inserter cartridge 92, the locating cylinder 94 is inserted into the receiving slot 98 of the docking member 97 until its cylindrical surface conformingly engages a terminal end 101 of the receiving slot 98. With the locating cylinder 94 in place, the two end plates (95, 96) also conformingly engage the top and bottom surfaces (99, 100) of the docking member 97, thereby completely fixing the position of the inserter cartridge on the docking member. As a result, if the inserter cartridge 92 needs to be replaced during a marking process, the replacement inserter cartridge can be precisely mounted in the same position for continued marking without significantly affecting the consistency and overall quality of the marks produced.
In a refinement, the locating cylinder 94 may also provided housing to the inserter 5. For example, the locating cylinder 94 may include a center bore in which the inserter 5 may be positioned using fixturing and fixed into place using an adhesive such as an epoxy.
Alternatively, the inserters 5 may in some embodiments be positioned and fixed in place by molding the locating cylinder 94 about the inserter 5. This can be achieved according to known processes in the injection molding industry where threads, pins, and even inserters are inserted into a mold cavity and a surrounding housing is injection molded into place.
In addition to the reference feature 93 described above, the inserter cartridge 92 may further include a locking feature 105 configured to lock the inserter cartridge 92 onto the identification device 3. Still referring to
To lock the inserter cartridge 92, the scotch yoke 102 of the identification device 3 includes a receiving opening 113 extending between front and back surfaces (114, 115), as illustrated in
One feature of the disclosed marking system is deposition of pigment with improved depth precision, such as by using the restraining device 2 and/or identification device 3 disclosed herein. For purposes of tattooing a mouse tail, the identification device 3 may need to drive the inserter 5 to the desired dermal layer depth, for example, 150-250 microns for young mice, and 200-300 microns for adult mice.
In one embodiment, the marking system comprises inserters that are capable of penetrating the marking substrate epidermis and transfer the pigment from the inserter into the dermal layer.
In one embodiment, the marking system is configured to deposit a pigment into the marking substrate at a depth of;
a. 150-250 microns for young mice.
b. 200-300 microns for adult mice.
c. 200-250 microns regardless of the age of the mice.
To meet this depth requirement and to produce a mark of sufficient font size to be legible to the unaided eye, the mark character must partially wrap the circumference of the tail and be at the target depth. This latter circumferential depth requirement may in some embodiments be achieved by pivoting the inserter 5 during the tattooing process about an arc whose center is coincident with the center of the mouse tail diameter, thus keeping the identification device normal to the surface of tail at all times. Maintaining the tattoo depth therefore is attained by programming the system processor to control the position of the robotic assembly 42 (whereon is attached the inserter 5), and providing a mounted inserter having a length controlled to ±25 microns and lateral centering within ±125 microns with respect to its pivoting axis.
It is conceivable that an inserter cartridge 92 can in some embodiments be alternatively designed to mount directly to the identification device 3 and forego the reference and/or locating features (93, 105). This configuration can be suitable and sufficient for low-volume tattooing requirements.
In the case of high-volume throughput requirements, it may be desirable to design a system wherein multiple inserter housings are mounted into, for example, a turret, which the marking system can in some embodiments access in order to replace inserters upon command, or on a preprogrammed basis.
The restraining device, useful according to the present disclosure, is any device that can restrain the body part of an animal to be marked. For example, in one embodiment the restraining device has a first part useful for restraining the main body of the animal, and a second part useful for restraining and presenting the body part to be marked to the identification device. Useful restraining devices include those that do not kill, harm, or cause undue duress or stress to the animal. Further useful features of the restraining device include said device's ability to compensate for variations in taper, girth, and/or other abnormalities of the tail.
In one embodiment, the marking system comprises one restraining device having a spring-loaded tapered v-groove to support the underside of the tail during marking and that is used to compensate for differences in size of the substrate body part while still enabling the marking system to maintain the target pigment depth of the marking.
In one embodiment, the marking system comprises a plurality of restraining devices each having a spring-loaded tapered v-groove of varying size to support the underside of the tail during marking and that are used to compensate for the range of differences in size of the substrate body part while still enabling the marking system to maintain the target pigment depth of the marking.
In one embodiment, the restraining device is comprised of a one-piece spring-loaded plate having a tapered v-groove supporting the substrate body part.
Optionally, the one-piece spring-loaded tapered v-groove plate is additionally enclosed within a protective compliant boot.
In one embodiment, the restraining device is comprised of a modulated spring-loaded plate that includes multiple independently articulating self-aligning spring-loaded, tapered v-groove sections, the combination of which comprise the tapered v-groove plate supporting the substrate body part.
Optionally, the multiple spring-loaded tapered v-groove sections are additionally enclosed within a protective compliant boot.

The body part cleat 10 may in some embodiments be fixed to the body restraint 22 such that the user can hold the entire restraining device in one hand with fingers (e.g. a thumb and an index finger) depressing tabs 74 of the body part cleat 10 to separate opposing members 11, 12 from each other. The user can then simultaneously restrain both trunk and the body part (e.g. tail) of the animal (e.g. mouse) simply by placing the restraining device over the animal such that the body part is positioned between opposing members 11, 12, and then releasing his fingers from tabs 74.
In one embodiment, such a restraining device 2 optionally provides rapid but secure immobilization of an animal. In one embodiment, such a configuration allows a user to operate a second restraining device with a second hand, to simultaneously restrain two animals.
Referring now to
Although the components of the restraining device 2 are in other embodiments directly supported by a primary baseplate 19 of the marking system 1 (
The marking system of the present disclosure may in some embodiments further include an optional measuring device 125 to measure the size of the marking substrate. For example, the measuring device 125 may in some embodiments be a mechanical gauge 126, such as a tail gauge, that can be used to measure the girth of a mouse tail for purposes of determining the appropriate restraining device and inserter necessary to achieve the appropriate depth of dermal layer placement of the marking pigment. An actual girth measurement is a more accurate and repeatable means of determining the appropriate restraining device and inserter combination than say age or weight of the animal. The girth of the tail at a particular age or weight will vary greatly depending on a number of factors, for example strain of mouse, gender, diet, litter size, etc.
In one embodiment, the girth of the mouse tail nearest the body is used to determine the optimal combination of inserter length and supporting v-groove in the restraining device to satisfy the marking target depth.
In one non-limiting embodiment illustrated in
Optionally, the grooves 127 of the tail gauge are or are about 0.094″, 0.105″, 0.115″, 0.128″, and 0.140″ in width, each approximately corresponding to the age and weight ranges of mice shown in the table below.
Optionally, the measurement is made manually by the user lowering the grooved gauge over the tail nearest the body of the mouse, and finding the smallest groove 127 that fits (i.e. drops) comfortably over the girth of the tail.
The girth measurement may in some embodiments alternatively be made in non-contact fashion by the marking system. In one embodiment, the marking system includes a laser-based measuring device 128 that measures the girth of the body part by using a laser light curtain and a receiver that is incorporated into the system, as schematically illustrated in
In a refinement of this embodiment, the measurement is made manually, by the user introducing the body part into the path of the light curtain.
In another refinement of this embodiment, the measurement is made automatically by breaking the path of the light curtain when the user introduces the restraining device into the marking system.
A cartridge removal tool 130, useful according to the present disclosure, may be optionally provided to remove the inserter cartridge 92 from the identification device 3. For example, when the inserter cartridge includes locking clips (e.g. pinch arms) that enable easily pushing-on and locking the inserter cartridge into place, the marking system may include an appropriately sized forked tool 130 for removal of the cartridge housing from the identification device, as illustrated in
Optionally, the forked tool 130 may be integrated with measuring tail gauge 126 used to determine the girth of the substrate body part, as illustrated in
In one embodiment, the controller 4 described herein is any controller that is able to control the position/movement of the robotic arm relative to the robot assembly and/or for actuating the identification device, for example a computer or microprocessor, or computer-interfacing device.
The present invention contemplates a computer program (e.g. recorded on a computer readable medium) comprising instructions for manipulating a robotic assembly to perform a function or method taught herein.
The controller manipulates the robotic assembly 42 to position the identification device 3 about the substrate and mark the substrate. The controller 4 can determine the position of substrate by existing instructions that informs the controller of the substrate's position.
In one embodiment, the controller 4 contains a program that is responsive to one or more feedback mechanisms (e.g. sensors).
In another embodiment, the controller 4 contains an algorithm such as PID to control one or more servo-based actuators (e.g. marking actuators).
The system controller 4 provides positioning and character mapping instructions to the inserter for producing the desired substrate marking. The direction of inserter travel relative to the substrate to be deposited can influence the results in some embodiments. In some embodiments, the identification device is operated by a controller to deposit the microelectronic chip in a proximal to distal direction parallel to the animal tail. In some embodiments, the microelectronic chip implant device is operated by the controller to implant the microelectronic chip in a distal to proximal direction parallel to the animal tail. In some embodiments, the microelectronic chip implant device is operated by the controller to implant the microelectronic chip vertical to the animal tail.
The marking system further includes a marking device to deliver a pigment to the marking substrate in some embodiments. The marking device and media transfer assembly are described in U.S. Provisional Application Nos. 61/637,767 and 61/239,430, both incorporated herein in entirety.
In practice, one embodiment of the process flow for independently combining the independent visual and electronic identification methods is diagrammatically illustrated in
In the case where the animal needs to be genotyped, a tissue sample may also be taken concurrently with the animal being tagged. The genotyping analysis is typically done at an independent laboratory, thus traceability of the sample needs to be tied to the tag implanted in the animal. The tissue sample may be collected in, for example a vial or a 96-well microtiter plate. The sample collection container may be tagged with a similar microelectronic chip, and both the animal and the container may be scanned to upload and associatively link the two identification numbers within the colony management software.
After genotyping, those animals that meet the test criteria are identified and reconciled or registered in the colony management software. These may proceed to be additionally identified with a permanent visual identification mark. Those not meeting the genotyping test criteria may or may not require a permanent visual identification mark.
For those animals requiring a permanent visual identification mark, this would be completed by introducing the animal into the automated tattoo system where either an external or integrated chip reader would read the animal tag. The identification management software would recognize the tag number from the post-genotyping reconciliation step, and assign an alpha-numeric visual identification number to be tattooed onto the animal. The alpha-numeric tattoo identification might or might not be the same, or a subset of, the electronic tag number, suffice the visual and electronic numbers would ever-after be associated via the identification management software.
In a further embodiment, the media transfer assembly containing the tattoo ink used to mark the animal may also be tagged as part of its manufacturing process using a similar microelectronic chip or an implanted bar-code in order to provide traceability and validation of all substances that come into contact with, or that is applied to, the animal.
