Abstract: A wireless wall mount for a remote control for use at an existing wall switch position to receive and support a wireless remote control, including a mounting fixture adapted to be attached to the wall switch at the position of the wall switch plate. The mounting fixture including an attachment structure for receiving and supporting the wireless remote control while allowing the removal of the remote control to other remote locations.

Abstract: Payload delivery of a payload compartment containing a delivery device is initiated by a suitable fusing device which ejects the delivery device from a payload section by firing a gas generator in the section base to propel the delivery device forwardly, thereby shearing retaining pins and ejecting the delivery device from the payload section. The fusing device concurrently fires a time-delayed mechanism leading to a second gas generator in the center of the delivery device. The gas generator ignites after the chaff dispenser is clear of the payload section. The ignition reaction pneumatically blows chaff (e.g. metallized dipoles) out of wrapped bundles, leaving the wrapper bonded to the delivery device and disseminating the chaff in a cloud of hot gas and air turbulently mixed in the wind shear occurring in the wake of the delivery device. The delivery device survives the dispensing and dissemination processes without losing structural integrity. Thus, no harmful debris is ejected into the chaff cloud.

Abstract: This invention relates to an improved drive and control means for matrix addressable electro-optic displays, such as passive matrix LCDs and active matrix LCDs. The present invention achieves improved drive and control of displays through the use of real time computation and memory circuits to simulate the electro-optic condition and the accumulated DC bias of individual display elements. This eliminates the burden of frequent and symmetrical reversals of the drive polarity, and allows the implementation of flexible DC drive methodologies.

Abstract: Each of first and second switches, preferably ganged, have first and second operative relationships. In the first operative relationship, the first switch is connected across a firing device to prevent the firing device from being energized. In the first operative relationship, the second switch is connected across an energy storage device (e.g. capacitor) to prevent the capacitor from being charged. In the second operative relationship of the second switch, the capacitor is charged by an energy supply device (e.g. battery). In the second operative relationship of the first and second switches, the capacitor is connected in a circuit with the first device and a third switch (e.g. transistor). The transistor is normally nonconductive to prevent the capacitor from discharging through the firing device with the first and second switches in the second operative relationships.

Abstract: Apparatus for, and a method of, facilitating the hearing of audio information by an individual are provided for the inner ear of the individual. The apparatus includes a prosthesis having a head portion and a body portion. The head portion may be provided with a flattened configuration shaped to confirm to a particular one of the malleus and the incus. The body portion of the prosthesis extends transversely from the head portion into the fluid in the inner ear. The prosthesis may be made from a suitable material such as a metal or a plastic having properties of transmitting sound from the middle ear to the inner ear. A heat shrinkable sleeve envelopes the head portion of the prosthesis and the particular one of the malleus and the incus. The sleeve may be shrunk as by heat to provide a pressed fit with the head portion of the prosthesis and the particular one of the malleus and the incus. The heat may be produced as by a laser.

Abstract: A pair of pivotable arms in a clamp in a personal trainer may be spring biased to a closed position as on a door frame. A lock retaining the clamp in the closed position includes a member manually actuatable to release the clamp from the door frame. A clasp on the clamp holds a first belt in a wrapped and frictional relationship. In one embodiment, the second end of the first belt is retained by a resistance unit which is disposed on a handle adapted to be manually gripped by the user. The resistance unit has bars which receive the belt in a frictional and tensioning relationship to retain the belt. Collars on the handle retain a harness shaped to envelope the user's face. The harness may be moved or rotated relative to the handle to exercise muscles in selective portions (e.g. neck or back) of the user's body. In another embodiment, a second belt engaged by the resistance unit extends beyond the resistance unit.

Abstract: A motor for impelling a missile or projectile has a housing and a plurality of spaced walls defining progressive compartments in the housing. A nozzle in one of the compartments produces a thrust for the missile or projectile when pressurized gases flow through it. Igniters extending into the individual compartments ignite propellants in such compartments. The igniter in an individual one of the compartments is energized initially and the igniters progressively displaced from such individual compartment are thereafter energized sequentially. Each wall separating an individual pair of adjacent compartments has a normally closed valve. Each valve has a first orifice of relatively great area in the compartment closer to the nozzle and a second orifice of limited area in the compartment further from the nozzle. A membrane between the orifices prevents the valve from being opened by a pressure from the closer compartment until this pressure becomes relatively great (e.g. 6500 psi).

Abstract: An apparatus and method for scanning a probe over a surface to either produce a measurement of the surface representative of a parameter other than the topography of the surface or to perform a task on the surface. The scanning operation is divided into two parts and with a first scan to obtain and store topographical information and with a second scan to measure the parameter of the surface other than topography or to perform the task while the probe height is controlled using the stored topographic information.

Abstract: A head records a track (e.g. a servo track) in a memory member outside of a clean room without using reference indices. In each of a plurality of cyclical movements (e.g. revolutions), signals (e.g. servo signals) are recorded in the track in an individual number of frames. Thereafter th e distance of the unrecorded portion of the track is determined. In the next cyclical movement, the head records signals in an individual number of frames contiguous to the frames previously recorded, in a track distance dependent upon such individual number relative to the number of frames still unrecorded and upon the distance determined for the unrecorded track portion. In a last cyclical movement, the head records a single frame in a particular spatial relationship with the first and last frames. In a specific embodiment, 2.sup.N-K frames may be recorded in the K cyclical movement. Additional signals may thereafter be recorded by the head in tracks in a single cyclical movement.

Abstract: A system on an integrated circuit chip for providing a digital-to-analog conversion includes a plurality of output members each providing a particular current when energized. These members may be disposed on the chip in a pair of spaced columns. First control lines in the space between the columns of output members provide a thermometer code. Second control lines in this space provide a binary code. The first and second control lines are preferably parallel to the columns. When a first one of the first control lines is energized, different ones or combinations of the second control lines provide progressive values in the output members between "0" and "15", assuming four (4) of the second control lines. Similarly, when a second one of the first control lines is additionally energized, different ones or combinations of the second control lines provide progressive values between "16" and "31" in associated output members. At the same time, the output members providing a value of "15" continue to be energized.
