DETAILED DESCRIPTION

Aspects of the disclosed predictive maintenance systems are described in detail with reference to the drawings, in which like reference numerals designate identical or corresponding elements in each of the several views. In addition, directional terms such as front, rear, upper, lower, top, bottom, and the like are used simply for the convenience of description and are not intended to limit the disclosure attached hereto.

In the following description, well-known functions or constructions are not described in detail to avoid obscuring the present disclosure in unnecessary detail.

Referring to FIGS. 1 and 3-8, a hands-free height measurement system 100 configured for measurement of a user or subject 20 is shown. The hands-free height measurement system 100 generally includes a body 110, a mounting flange 120, a distance sensor 150 configured to sense a distance from the system 100 (e.g., a bottom-most surface, or ground facing surface) to an object (e.g., such as the user or subject 20 or the floor), a motion sensor 152 configured to sense motion of the user or subject 20, a visual indicator 154 (e.g., a LED), a speaker 132 configured to emit sound (e.g., a voice announcing the measured value), and a controller 200 configured to process sensor signals and determine a height of the user or subject 20.

The body 110 of the hands-free height measurement system 100 generally includes a top surface 116, a bottom surface 114, and an end surface 112. In aspects, the top surface 116 may include a speaker grille 130 configured to protect a speaker 132 and to permit the emission of sound from the speaker 132. In aspects, the distance sensor 150, the motion sensor 152, and the visual indicator 154 may be disposed on the bottom surface 114 of the body 110.

The mounting flange 120 is configured for mounting the hands-free height measurement system 100 to a wall 10 or other surface for mounting (e.g., a mirror, a stand, a door, a post, etc.). The mounting flange 120 may include a suction cup, double-sided adhesive, and/or holes for mounting hardware to enable mounting the hands-free height measurement system 100 at a suitable height (e.g., 2 meters from a floor) for determining the height of the user or subject 20 during operation/use thereof.

The distance sensor 150 (FIGS. 7 and 8) may include an ultrasonic distance sensor, an IR proximity sensor, and/or a laser distance sensor. The distance sensor 150 functions by outputting a signal (depending on technology; ultrasonic waves, IR, LED, etc.) and measuring the change when the signal returns. Measurement of change can be in the form of the time it takes for a signal to return and/or the intensity of a returned signal.

The motion sensor 152 is configured to detect the presence of a user or subject 20. A detected motion, by the motion sensor 152, is communicated to the controller 200 and may be used to initiate a height measurement of the user or subject 20 when the user or subject 20 enters a sensing zone for motion sensor 152. The motion sensor 152 may include active and/or passive motion sensors.

The visual indicator 154 is configured to provide a visual indication of detected motion and/or provide an indication that the system 100 is determining a height of the user or subject 20. The visual indicator 154 may also provide a visual indication that the height of the user or subject 20 is above a threshold value. For example, the visual indicator 154 may turn red if the height of the user or subject 20 is below the threshold value and green if the height of the user or subject 20 is above the threshold value. Further, the visual indicator 154 may display alpha-numeric charaters (e.g., distance in metric or non-metric/English units) to convey to the public the height information measured.

The speaker 132 is configured to emit a sound. For example, the controller 200 may communicate a signal to the speaker 132 to indicate the height of the user or subject 20 and/or whether a user or subject 20 is taller than a predetermined height (e.g., a voice announcing the measured value). The indication may include a tone (e.g., a beep) and/or a voice.

In aspects, the system 100 may be mounted at a predetermined height, for example, at two meters high, and the predetermined height may be stored by the controller 200 as a calibration distance. In aspects, the system 100 may be calibrated by measuring a distance from a bottom-most surface of the system 100 to the ground and storing the measured distance as the calibration distance.

In use, the controller 200 is configured to subtract a measured height/distance from the stored calibration distance. For example, a measure/distance from the top of a head of a user or subject 20 and subtract the measured distance to the the head of the user or subject 20 from the distance to the ground. For example, if the system 100 is mounted seven feet (e.g., 7.0 feet) high from the ground, when calibrated the controller 200 measures and stores the measured distance from the ground (e.g., 7.0 feet), then a user or subject 20 would stand under the system 100 and the motion sensor 152 would detect the motion of the user or subject 20 and cause the controller 200 to measure the distance to the top of the head of the user or subject 20 (e.g., about 2.0 feet). The controller 200 would then subtract the two-foot (2.0 feet) distance (e.g., distance to the top of the head of the user or subject 20) from the seven-foot (7.0 feet) distance (e.g., distance to the ground) and calculate that the user or subject 20 is five feet (5.0 feet) tall. Then the controller 200 provides audio notification, for example, by announcing the height of the user or subject 20, e.g., “you are five feet tall,” or “five feet, zero inches.”

In aspects, the system 100 may be used in amusement parks for determining if a user or subject 20 meets the height requirements for a ride or attraction. The controller 200 may compare the measured height to a predetermined number or threshold values (e.g., the height requirement for a ride) and provide an audio indication as to whether the user or subject 20 meets and/or exceeds the predetermined number. For example, the audio notification may announce “pass” or “fail,” or “you meet/do not meet the requirements to ride this ride.”

In aspects, the hands-free height measurement system 100 may be powered by batteries 140 or may be AC powered.

FIG. 2 illustrates that controller 200 includes a processor 220 connected to a computer-readable storage medium or a memory 230. The computer-readable storage medium or memory 230 may be a volatile type of memory, e.g., RAM, or a non-volatile type of memory, e.g., flash media, disk media, etc. In various aspects of the disclosure, the processor 220 may be another type of processors such as a digital signal processor, a microprocessor, an ASIC, a graphics processing unit (GPU), a field-programmable gate array (FPGA), or a central processing unit (CPU).

The CPU is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions, and by way of non-limiting examples, include server computers. In some aspects, the controller includes an operating system configured to perform executable instructions. The operating system is, for example, software, including programs and data, which manages hardware of the disclosed surgical stapling apparatus and provides services for execution of applications for use with the disclosed surgical stapling apparatus. Those of skill in the art will recognize that suitable server operating systems include, by way of non-limiting examples, FreeBSD, OpenBSD, NetBSD®, Linux, Apple® Mac OS X Server®, Oracle® Solaris®, Windows Server®, and Novell® NetWare®. In some aspects, the operating system is provided by cloud computing.

In some aspects, the term “controller” may be used to indicate a device that controls the transfer of data from a computer or computing device to a peripheral or separate device and vice versa, and/or a mechanical and/or electromechanical device (e.g., a lever, knob, etc.) that mechanically operates and/or actuates a peripheral or separate device.

In aspects, the controller includes a storage and/or memory device. The storage and/or memory device is one or more physical apparatus used to store data or programs on a temporary or permanent basis. In some aspects, the controller includes volatile memory and requires power to maintain stored information. In various aspects, the controller includes non-volatile memory and retains stored information when it is not powered. In some aspects, the non-volatile memory includes flash memory.

The controller may include or be coupled to a server and/or a network. As used herein, the term “server” includes “computer server,” “central server,” “main server,” and like terms to indicate a computer or device on a network that manages the surgical stapling apparatus, components thereof, and/or resources thereof. As used herein, the term “network” can include any network technology including, for instance, a cellular data network, a wired network, a fiber optic network, a satellite network, and/or an IEEE 802.11a/b/g/n/ac wireless network, among others.

In various aspects, the controller can be coupled to a mesh network. As used herein, a “mesh network” is a network topology in which each node relays data for the network. All mesh nodes cooperate in the distribution of data in the network. It can be applied to both wired and wireless networks. Wireless mesh networks can be considered a type of “Wireless ad hoc” network. Thus, wireless mesh networks are closely related to Mobile ad hoc networks (MANETs). Although MANETs are not restricted to a specific mesh network topology, Wireless ad hoc networks or MANETs can take any form of network topology. Mesh networks can relay messages using either a flooding technique or a routing technique. With routing, the message is propagated along a path by hopping from node to node until it reaches its destination. To ensure that all its paths are available, the network must allow for continuous connections and must reconfigure itself around broken paths, using self-healing algorithms such as Shortest Path Bridging. Self-healing allows a routing-based network to operate when a node breaks down or when a connection becomes unreliable. As a result, the network is typically quite reliable, as there is often more than one path between a source and a destination in the network. This concept can also apply to wired networks and to software interaction. A mesh network whose nodes are all connected to each other is a fully connected network.

In some aspects, the controller may include one or more modules. As used herein, the term “module” and like terms are used to indicate a self-contained hardware component of the central server, which in turn includes software modules. In software, a module is a part of a program. Programs are composed of one or more independently developed modules that are not combined until the program is linked. A single module can contain one or several routines, or sections of programs that perform a particular task.

As used herein, the controller includes software modules for managing various aspects and functions of the disclosed surgical stapling apparatus or components thereof.

The disclosed structure may also utilize one or more controllers to receive various information and transform the received information to generate an output. The controller may include any type of computing device, computational circuit, or any type of processor or processing circuit capable of executing a series of instructions that are stored in memory. The controller may include multiple processors and/or multicore central processing units (CPUs) and may include any type of processor, such as a microprocessor, digital signal processor, microcontroller, programmable logic device (PLD), field programmable gate array (FPGA), or the like. The controller may also include a memory to store data and/or instructions that, when executed by the one or more processors, cause the one or more processors to perform one or more methods and/or algorithms.

Any of the herein described methods, programs, algorithms or codes may be converted to, or expressed in, a programming language or computer program. The terms “programming language” and “computer program,” as used herein, each include any language used to specify instructions to a computer, and include (but is not limited to) the following languages and their derivatives: Assembler, Basic, Batch files, BCPL, C, C+, C++, Delphi, Fortran, Java, JavaScript, machine code, operating system command languages, Pascal, Perl, PL1, scripting languages, Visual Basic, metalanguages which themselves specify programs, and all first, second, third, fourth, fifth, or further generation computer languages. Also included are database and other data schemas, and any other meta-languages. No distinction is made between languages which are interpreted, compiled, or use both compiled and interpreted approaches. No distinction is made between compiled and source versions of a program. Thus, reference to a program, where the programming language could exist in more than one state (such as source, compiled, object, or linked) is a reference to any and all such states. Reference to a program may encompass the actual instructions and/or the intent of those instructions.
