Abstract: A split keyboard with an optional middle section of keys for controlling regular PC input to a host, to play music, and to input and play music with a multiple octave keyboard that when the middle section of keys are removed can be portable to travel. And when working on just the split keyboard inputting data to a host the operator arms are not abducted due to the perpendicular advantage or slide apart keyboard where an operators arms are perpendicular to the keyboard keys.

Abstract: A key switch to sense and give feedback to a computer of depth, acceleration, velocity, and lateral or vibrato movement. The key switch is suitable for computer keyboards, musical keyboards, foot pedals and the like. Lateral or sideward key movements can be for mouse functions or multi code output from multi directional key movement from one key outputting a single key code or key sequences.

Abstract: An electronic sketch pad and auxiliary monitor to be used as a peripheral to personal computers. The electronic sketch pad and auxiliary monitor slides under or attaches to the computer keyboard and is used as an auxiliary monitor to the primary CRT monitor. The electronic sketch pad is above and parallel to the key tops, and can be adjusted to give enough room so you can still operate the keyboard. If you are video teleconferencing with a client or colleague you can sketch an idea on the electronic sketch pad and send it without interrupting your primary monitor screen. The operator can move the electronic sketch pad from an optimal sketch position to an optimal auxiliary monitor position below the primary monitor. Now while having a WEB screen on the primary monitor you can be taking notes, doing word processing or working other programs on the auxiliary monitor.

Abstract: A cursor positioning device that can be sealed if the environment requires sealing, that can withstand harsh use, and can position the cursor easily and quickly. In operation the where the operator places their fingers on the positioning articulator and rocks or slides the articulator in the direction they want the cursor to move. And with movement signatures do single and double clicks, and character strings to the host computer, either through the mouse port or the keyboard port. The key and articulator interrupters block optical beams for key and mouse like positioning thus eliminating any physical contact or force from articulator to detecting optics. Cursor position is positioned by an interrupter disposed in a ring of optical emitters and detectors, whereas depending on the position of movement by the positioning interrupter emission is blocked, or partially blocked, between a particular pair or pairs of emitters and detectors, that particular pair or pairs being the direction of cursor movement.

Abstract: A rugged keyboard and cursor positioning device with an inherent restiveness from external fluids to interior keyboard fluid contamination. The key interrupters and cursor positioning device block optical beams for key and cursor positioning detection thus eliminating contacts and contact actuation life. When a key is in the most depressed position the key cap is against the keyboard top surface protecting all internal parts from pressure, or force from harsh use or a vandals blow.

Abstract: An electronic circuit for use in a monocular night vision device for electronically controlling a plurality of components within the device, the device having an objective lens assembly for receiving low intensity light, a variable gain image intensifier tube having a user adjustable variable gain controller external to the tube for adjusting the light intensity level of a visible output image, a single eyepiece lens assembly for viewing the output image from the image intensifier assembly; and a non-metallic housing comprising an upper housing for receiving the objective lens assembly, image intensifier assembly, and eyepiece lens assembly, and a lower housing containing a battery cavity for receiving batteries to power the device. The housing aligns the objective lens assembly with the image intensifier assembly and the eyepiece lens assembly along an optical axis wherein the upper and lower housing are coupled to one another along the optical axis.

Abstract: A method for providing user adjustable variable gain for a night vision device which utilizes an image intensifier tube, wherein the image intensifier tube has a given life expectancy, the image intensifier tube is subjected to factory calibration for providing an optimum output during operation, wherein the calibration undesirably differs from tube to tube and is adjustable by variable control means coupled to the tube, whereby when one tube is substituted for another the difference in calibration causes non-optimum performance, the method including the steps of: determining minimum and maximum gain limits associated with the optimum output of the night vision device; factory calibrating gain limiting means according to the determined minimum and maximum gain limits, wherein the gain limiting means are associated with the image intensifier tube and for limiting the variable control means; and, tethering the gain limiting means to the image intensifier tube.

Abstract: A keyboard where no finger pressure is needed to input data, that uses rows of emitters opposed by rows of detectors to detect a finger position, that is environmentally sealed, and inherently intrinsic safe. The keyboard has a mouse function so an operators finger can be tracked to position a cursor on a host display, and input normal keyboard functions. A sleep mode for a display or keyboard that slows down the scan rate and emitter intensity to increase emitter life. A split keyboard for each hand with an arm rest with an arm strap to attach the keyboard to an operators arm and a strap to attach the keyboard to the arm of a chair. A learning keyboard with a mode for QWERTY or other key pattern keyboards that the position of the operators fingers are tracked and supper imposed on a display, so the operator can see when their finger is over the correct keyboard indicia so correct data entry can be made without looking at the keyboard.

Abstract: A handle assembly, especially useful on power line trimmers, includes a fore arm rest or fore arm "contacting element" which retains the user's arm, a first handle positioned directly in line with a trough in said fore arm rest, and a second handle positioned to a side of the fore arm rest and first handle. In operation, the user's first hand and fore arm act in concert to direct the power tool, while the user's second hand acts to sweep the power tool from side to side, whereby the user's fore arm acts as a fulcrum at the fore arm rest of the handle assembly. By providing three points of contact with the user, the handle assembly allows the user to engage in a sweeping motion that is less strenuous and more easily controlled. In addition, the handle assembly provides better balancing of the power tool, and assists in maneuvering the power tool.

Abstract: A keyboard to be used on an operators lap that separates to relieve stress in an operators neck and wrists. The keyboard has a flat surface between the keyboard sides, so while being held on a persons lap, will hold reference material and a second party pointing device that can be used with either hand to keep the neck straight. A notebook computer with keyboards that open up on each side so the operators hands are separated. The keyboards can slide closed or fold closed, and when folded, interleave so full size keys can be used and facilitate a more compact design, and can be unfolded so the keyboards slant down below the computer or keyboard to centralize the computer on a persons lap, and reduce the twist between the hand and wrist. The keyboard includes a device to turn all visual indication of computer operation off to be used in a secure no light area with a speaker to give verbal enunciated messages in response to the keyboard and from a computer.
