2. Description of the Prior Art
The ability of a remote apparatus to effectively achieve its targeted tasks is dependent, in large part, on communication systems and a user interface. The human machine interface and related controls are critical to successful tele-operated and semi-autonomous operations. The human operator has the adaptability needed in a dynamic, unpredictable environment. However, the operator's cognitive, motor, and peripheral senses are limited even under optimal conditions. Accordingly, designing the remote apparatus platform control interface and integrating this interface must take into consideration these limitations in order to optimize the quality and effectiveness of the human/machine interface.
One objective to optimize the quality and effectiveness of the human-machine interface is for the user interface to provide a wide range of human/robot interaction modalities. For example, when interacting with a fully autonomous tactile mobile robot or unmanned vehicle, the communication from the robot may merely consist of a situation report at a way point. In this case, the human response could be a software recognized hand signal instructing the robot to continue on to the next way point. Conversely, the other end of the spectrum of interaction modalities occurs when autonomous functionality is not appropriate or not operational. Non-autonomous interaction would likely require a live video feed from the robot as well as telemetry data. The operator would need to directly control the mobility of the robot with some type of proportional input, such as a small joystick or tactile sensor.
Accordingly, there is a need for a system that supports control of a remote apparatus while supporting motor skills and cognitive abilities of the operator.
This invention comprises an apparatus and method for a weapons mounted communication system.
In one aspect of the invention, an apparatus is provided with a control module operable to generate at least one signal for transmission to a processing unit. The control module is mountable on a weapon. The control modules includes a housing that is configured as a vertical handgrip of the weapon with an electronic communication circuit mounted within the housing. An input device is coupled to an electronic input circuit and is mounted on the housing so as to enable the operator of the module to simultaneously operate the weapon and provide input to the processing unit. In addition, a receiver is provided to communicate with the processing unit to receive data generated by the input device and to convey the received data in a tactile format to an output device that is in communication with the processing unit.
In another aspect of the invention, a communication system is provided with a transceiver in the form of a control module mountable to a weapon and a receiver in the form of a processing unit in communication with the transceiver. An input device is present in the system and coupled to the transceiver. The input device supports simultaneous operation of both the weapon and the processing unit. In addition, a tactile output device is provided in communication with the transceiver to provide tactile output to an operator in response to a signal received from the transceiver.
Other features and advantages of this invention will become apparent from the following detailed description of the presently preferred embodiment of the invention, taken in conjunction with the accompanying drawings.
The mounted isometric controller (MIC) is a control module in the form of an isometric joystick mounted to a weapon. The control module generates communication signals that are received by a processing unit that may be remote from or local to the module. The control module is mountable on the weapon and is also detachable from the weapon, and is operable in both positions. When the control module is in a position in which it is mounted to the weapon, it supports simultaneous operation of the weapon and input to the processing unit. The control module is isometric in that it detects forces applied by the user without moving at such time as it is in a mounted position. Similarly, when the control module is detached from the weapon, it maintains communication with the processing unit.
The mounted isometric controller (MIC) consists of a control module having vertical body that is mountable to a rail attachment of a weapon. In a mounted position, the MIC may be used as a hand grip to hold the weapon in a set position for firing, and at the same time, it may be used as a control module for communicating with a processing unit. In one embodiment, the processing unit may be a personal digital assistant, a remote apparatus, or an interface.
Additional control input elements for communicating with a processing unit are spaced apart along the length of the elongate body (15) between the top surface (20) and the bottom surface (30). The control input elements include a capacitive sensor (24), a set of input sensors (26), an isometric joystick (28), and a tactile controller (32). The capacitive sensor (24) activates a controller for the control module when an operator has a finger on or within close proximity to the sensor (24). Similarly, the capacitive sensor (24) deactivates the controller for the control module when the finger of the operator is not in close proximity to the sensor (24). In one embodiment, the capacitive sensor (24) is sized and positioned to receive the thumb of the operator. Situations that may result in removal of the thumb from the capacitive sensor include non-use of the weapon, or movement of the thumb of the operator into a firing position. Accordingly, the capacitive sensor (24) functions to enable or disable communication of data generated from one or more sensors of the elongate body (15) or forces on the elongate body (15) as read by the load sensing cell based upon how fingers of a soldier or other user are positioned with respect to the capacitive sensor (24).
In addition to the capacitive sensor (24), sensors (26) are spaced at preset intervals along the length of the vertical body (15). In one embodiment, the sensors (26) are binary buttons in communication with the controller to communicate binary data via a transceiver (not shown) based upon depression of the buttons. The sensors (26) may be mounted with respect to the control module in one of three positions, raised, flush, or recessed. The recessed position of the sensors (26) allow the fingers of the operator to bridge over the sensors (26) unimpeded when the operator is using the control module body (15) to fire the weapon. At the same time, the recessed nature of the sensors (26) allows for easy access when the vertical body (15) is being used as a controller in communication with a remote apparatus. In addition to the sensors (26), a secondary joystick (28) is provided along the body of the control module (15) to communicate with the processing unit (502). The secondary joystick (28) is an input device to communicate proportional data with the processing unit (502). In one embodiment, the secondary joystick (28) is comfortably accessible to the user's thumb and is mounted on an upper rail attachment element to provide to minimize unintended forces on the load sensing cell (40) of the elongate body.
As shown in
As noted above, each of the switches, sensors, and joysticks placed along the vertical body (15) forward their data to a processing unit. The processing unit parses the received data and either utilizes the parsed data or transmits the data.
As shown in
The control module (15) with it's load sensing cell (40), binary input sensors (26), secondary joystick (28), and tactile controller (32) improves the ease and utility of using a front weapon mounted controller. When the control module is secured to the rail attachment of the weapon, the load sensing cell (40) together with the binary input sensors (26) and the secondary joystick (28) function to convey data to the remote apparatus. Similarly, the control module (15) may be detached from the weapon and continue to communicate with the remote apparatus. For example, when the control module (15) is detached from or otherwise not attached to the rail of the weapon, the binary input sensors (26) and the secondary joystick (28) continue to convey data to the remote apparatus, however, the load sensing cell (40) becomes disabled. This enables the control module to function as a portable communication tool with the remote apparatus.
The invention can take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment containing both hardware and software elements. In a preferred embodiment, the invention is implemented in software, which includes but is not limited to firmware, resident software, microcode, etc.
Furthermore, the invention can take the form of a computer program product accessible from a computer-usable or computer-readable medium providing program code for use by or in connection with a computer or any instruction execution system. For the purposes of this description, a computer-usable or computer readable medium can be any apparatus that can contain, store, communicate, propagate, or transport the program for use by or in connection with the instruction execution system, apparatus, or device.
The medium can be an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system (or apparatus or device) or a propagation medium. Examples of a computer-readable medium include a semiconductor or solid state memory, magnetic tape, a removable computer diskette, a random access memory (RAM), a read-only memory (ROM), a rigid magnetic disk and an optical disk. Current examples of optical disks include compact disk-read only memory (CD-ROM), compact disk-read/write (CD-R/W) and DVD.
A data processing system suitable for storing and/or executing program code will include at least one processor coupled directly or indirectly to memory elements through a system bus. The memory elements can include local memory employed during actual execution of the program code, bulk storage, and cache memories which provide temporary storage of at least some program code in order to reduce the number of times code must be retrieved from bulk storage during execution. Input/output or I/O devices (including but not limited to keyboards, displays, pointing devices, etc.) can be coupled to the system either directly or through intervening I/O controllers.
Network adapters may also be coupled to the system to enable the data processing system to become coupled to other data processing systems or remote printers or storage devices through intervening private or public networks. Modems, cable modem and Ethernet cards are just a few of the currently available types of network adapters.
The control module may be mounted to a rail attachment of a weapon. This configuration enables a soldier or other operator of the weapon to use the control module as both a communication tool and a weapon support element. At such time as the control module is mounted to the rail attachment, the sensors and buttons placed along the body of the module as well as the load sensing cell may be utilized to communicate with an output device through a remote apparatus. Each of the input elements mounted along the length of the body are isometric, i.e. stationary or fixed, thereby making the grip of the control module easy to use as both a stationary handgrip and as a controller. In addition, the load sensing cell located at the interface of the rail attachment and control module body gathers data associated with forces applied to the control module. Thus, the body of the control module is a control input sensor. The combination of the strain gauge together with one or more external sensors mounted along the body of the control module enables the control module to be used as a three axis input apparatus while allowing simultaneous access to control of secondary sensors, a two axis joystick, and a tactile mode selector.
It will be appreciated that, although specific embodiments of the invention have been described herein for purposes of illustration, various modifications may be made without departing from the spirit and scope of the invention. In particular, the vertical body may be dismounted from the weapon rail attachment and attached to a secondary location. Detachment of the control module body from the weapon rail attachment disconnects functionality of the strain gauge while enabling each of the externally mounts input sensors to remain in communication with the remote apparatus. Additionally, the tactile controller (32) may be used to switch the functionality of one or more of the sensors of the control module. For example, different positions of the tactile controller (32) may enable or disable select sensors, and/or switch communication of data received from a sensor to a different output. In addition, the indentations formed along the body of the control module are set to accommodate both left handed and right handed individuals. In one embodiment, the tactile controller (32) may be in the form of a wheel switch. The term weapon as used herein may be applied to various categories of firearms including, but not limited to, rifles, shoulder launched missiles, sub-machine guns, grenade launchers. Accordingly, the scope of protection of this invention is limited only by the following claims and their equivalents.
