Abstract: The battery pack retention apparatus, described herein, is an injection molded part. The injection molded part includes a rear housing (200) for a radiotelephone (100), two rails, (201, 203) for a battery pack (101) to slide along and six guide bars (207, 209, 211, 213, 215, 217) for retaining the battery pack (101) on the radiotelephone (100). Four of the six guide bars are the compliance type. The compliance-type guide bars (207, 211, 213, 217) have a U-shape and are coupled to the rails. A channel (401) is cored out from the rails under the compliance-type guide bars to allow for deflection of the guide bars. Deflection is caused by the bullets (409) of the battery pack (101) when the battery pack (101) is fully inserted. The deflection (y) of the guide bars provides a calculated force upon the battery pack (101). This calculated force ensures a high quality electrical connection between the contacts of the battery pack and the contacts of the radiotelephone.

Abstract: An air directional louver device, which incorporates one or more multi-grooved ratchet style notches to cooperate with corresponding mating fixed knife edge to mesh together.   Once the rotating ratchet grooves on the louver's axles and one or more fixed knife-edge pointer are meshed,  the louver can be held better in the last desired air direction set position than without the ratchet and pointer.  The rotating ratchet will help prevent also vibration and/or the forced air to the louver or to the fixed knife-edge pointer area from moving the louver frame to another undesirable position.  The fixed knife edge pointer, in another embodiment, will be rounded at its point for smoother operation and applied into the louver's corresponding holding area.  Further increase in the friction to change the louver position from one notch to another is attained by rounding the point and deepening the notches if desired.

Abstract: A signal adding device for adding n input signals, comprising n A/D converters, a selector, and a lowpass filter.      The n input signals are sampled in sequence by the A/D converter and digitized. Each digitized data is time-division multiplexed by the selector and input to the lowpass filter.      The lowpass filter eliminates unnecessary higher-frequency components that are generated by the sampling of the A/D converter. The signal output from the lowpass filter consists of the baseband components only, that is, the signal is equal to an added signal of n input signals.

Abstract: Analog and digital video signals are each representative of a picture and each may carry program guide information. A demultiplexer has the digital video signal as an input and the program guide information as an output. A demodulator has at least a luminance component of the analog video signal as an input and the program guide information as an output. A microprocessor, a video graphics adapter, the demultiplexer and the demodulator are interconnected by a data bus. Either of the program guide outputs is transferable to the video graphics adapter, which formats a graphics video signal representative of the program guide information. The graphics video signal and a selected one of the video signals are inputs to a multiplexes, which outputs a combined video signal representative of both the program guide information and the picture represented by the selected video signal.

Title: Differential drive system for an ink jet printhead
Inventor: STORTZ JAMES L
IPC: B41J2/045
Filed: 1994-05-03
Granted: 2000-02-15
Abstract: A differential drive system is used to actuate an ink jet printhead having a spaced, parallel series of internal ink receiving channels opening outwardly through ink discharge orifices formed in the printhead body. The channels are laterally bounded by a spaced series of piezoelectrically deflectable internal sidewall actuator sections of the printhead body interdigitated with the channels. The printhead body is specially configured to facilitate wiring access to spaced apart first and second electrical connection portions on each of the actuators. Electrical leads from a first controller are connected to the first actuator portions and are ganged in groups that are selectively connected to a driving voltage source, or to ground, by the first controller. A second controller has a first set of electrical leads similarly ganged in groups and connected to a first set of the second actuator portions, and a second set of unganged electrical leads individually connected to the rest of the second actuator portions. The second controller is operative to selectively connect any of its individual leads, or any of its ganged lead groups, to the driving voltage source or to ground. In conjunction with the dual controllers, this combination of ganged and individually addressable leads connected to the first and second actuator portions permits the actuators to be differentially driven in a manner digitally synthesizing a more complex bipolar drive system.

Abstract: Unusually strong and highly perforated plates are formed by pressurized filtration of a suspension of chopped ceramic fibers in an aqueous dispersion of colloidal alumina or colloidal silica through a mold (10) having a perforated filter base (20) and a pin support base (12) having pins (14) that extend through and beyond the perforations (25) of the filter base (20).        Pressurized filtration is preferably conducted by applying vacuum on the downstream side of the mold. When the resulting compact layer of chopped fibers (24) deposited on the perforated filter base (20) has the desired thickness, filtration is stopped. The perforated filter base (20) and pin support base (12) are moved apart to retract the pins (14) from contact with the perforated compact layer of chopped fibers (24) which is transferred to a drier. By operating the drier at a temperature not exceeding about 650°F (343°C), the compact layer of chopped fibers (24) is converted into a novel unsintered, perforated plate of unusual strength.

Abstract: Measuring the level in a container is done by means of a sensor fitted above the highest  level occurring and measuring the distance to the surface of the material in the container. An evaluation  circuit  computes  the  level  from  the  distance measured by the sensor and the empty distance.  The material volume is determined from the relationship between level and material volume  memorized  in  the  evaluation  circuit.  For calibrating a sensor in the case of an unknown empty distance, without having to completely empty the container, the on-going filling or emptying of the container is interrupted and the actual material volume is recorded.  Using the sensor to be calibrated a distance measurement is implemented and the actual material  volume  is  entered  in  the  evaluation circuit.  The evaluation circuit determines on the basis of the memorized relationship  between  level  and  material  volume  the  level belonging to the entered material volume and computes the empty distance as the sum from said level and the ranging result. In this way calibration is possible at a single calibration point without having to change the level in the container.
