Title: Hybrid bipolar/field-effect power transistor in group iii-v material system
Inventor: LARSON LAWRENCE E
IPC: H01L29/73
Filed: 1993-12-17
Abstract: HYBRID BIPOLAR/FIELD-EFFECT POWER TRANSISTOR IN GROUP III-V              MATERIAL SYSTEM         ABSTRACT OF THE DISCLOSURE     A hybrid power transistor (40) includes a vertical PNP bipolar transistor (42) having a floating base (46).  A junction-gate type field-effect transistor (FET) (62) has a lateral N-type channel (64,66) and a vertical electron injection path (54) from the channel (64,66) into the base (46) of the bipolar transistor (42).  The FET channel current and thereby the electron injection current are controlled by the FET gate voltage.  The injection current conductivity modulates the base (46) and thereby controls the collector current of the bipolar transistor (42).  The FET (62) may have a high electron mobility transistor (HEMT), junction-gate field-effect transistor (JFET) or metal-semiconductor field-effect transistor (MESFET) structure.  The FET (62) does not require a gate insulating layer, enabling fabrication of the hybrid transistor (40) in the group III-V material system.

Abstract: A simple and economical six-bar linkage system keeps a reclining chair (10) stable in its closed position, and permits it to assume any degree of recline between slight recline and full recline without need for friction devices or springs. This is accomplished by the stable balance of the linkage. Sequencing devices are likewise not needed; interaction of the components constrain the movement of the linkage, such that there is only one possible path of travel. The six links are: base frame (12), back frame (14), seat frame (16), drive link (18), carrier link (22), and legrest (20). A heart-rest po-sition may be attained with assistance from an attend-ant.

Filed: 1990-09-04
Abstract: ABSTRACT            An acoustic position sensing apparatus is described which determines the position of an indicator in relation to a datum surface  or volume.   The apparatus  comprises  an acoustic point source transmission device mounted on the indicator  for  transmitting  a  sequence  of  periodic acoustic oscillations, and a plurality of acoustic point receivers  positioned  about  the  datum  surface  for receiving the  acoustic  oscillations.   Comparators  are connected to each acoustic receiver for converting the received acoustic oscillations to square waves having logical up and down levels.  A register or other time determining circuit is coupled to each comparator and receives at least a leading portion of a square wave and provides an output if  it determines that the portion exhibits  one  of  the  aforesaid  logical  levels  for  a predetermined time duration.  A processor is responsive-to the outputs from the registers to find the position of the indicator.            The  acoustic  point  source  transmission  device  is configured both  as  a  linear  stylus  and  as  a  planar "puck",  both  having  at  least  a  pair  of  acoustic transmitters.  The apparatus employs, for two dimensional position detection,  at least three acoustic receivers arranged in a non-linear fashion.  A three dimensional position detector system is described which employs four receivers, three of which are oriented in one plane and a fourth in another plane.

Title: Method and apparatus for synchronizing a simulcast transmission system
Inventor: GOLDBERG STEVEN J
IPC: H04H20/67
Filed: 1993-05-07
Abstract: A simulcast system has a terminal controller (226) capable of measuring propagation delays, and calculating propagation delay differences from the measured propagation delays (1702) for each of the plurality of base sites (1602, 1604, 1606, 1608). The terminal controller (226) also receives and transmits data to each of the plurality of base sites (1602, 1604, 1606, 1608). The terminal controller (226) transmits the propagation delay differences, and a start command to the plurality of base sites (1602, 1604, 1606, 1608) for initiating simulcast retransmission of the data. The plurality of base sites (1602, 1604, 1606, 1608) also receive the propagation delay differences, the propagation delay difference (1706) being determined for delaying the retransmission of data at each of the plurality of base sites (1602, 1604, 1606, 1608).  The plurality of base sites (1602, 1604, 1606, 1608) receive data from the terminal controller (226) to be retransmitted. The plurality of base sites (1602, 1604, 1606, 1608) stores the received data and receive the start command. The retransmission of the stored data is delayed from the receipt of the start command (1720) by the propagation delay difference calculated for each base site to enable the retransmission of the data at substantially the same time by the plurality of base sites (1602, 1604, 1606, 1608).

Title: Hybrid adaptive allocation for audio encoder and decoder
Inventor: DAVIDSON GRANT ALLEN
IPC: H04B1/66
Filed: 1994-07-14
Abstract: The invention rotates in general to low bit rate encoding and decoding of information such as audio information. More particularly, the invention relates to adaptive bit allocation and quantization of encoded information useful in high-quality low bit rate coding systems. In an encoder a hybrid of forward-adaptive and backward-adaptive allocation is used to adaptively quantize information and to prepare an encoded signal which requires minimal side information to convey explicit allocation information to a companion decoder. In a decoder, a hybrid allocation technique is used to obtain allocation information required to dequantize information from a received encoded signal.
