Title: Photoconversion device
Inventor: SHINOHARA MAHITO
IPC: H01L27/146
Filed: 1991-08-06
Granted: 1998-02-03
Abstract: A photoconversion  device  comprises  a  plurality  of cells 1  each having a bipolar type sensor element T, the base of which is connected to a reset switch FET M and   is   also  capacitively  coupled  to  a  control electrode.  The device is  read  out  by  providing  a positive pulse to the base of the sensor T through the control  electrode,  and  is  refreshed  by  a   first operation  in  which the base is set to a preset level through the FET M and a second operation in which  the base-emitter  junction  of  the  sensor  T  is forward biased.  A control terminal 19 provides a  high  level reset  voltage to a main electrode region of the FET M through an emitter follower arrangement 18 to turn the FET  M  on  for  the  first  reset  operation  without providing a negative pulse  on  the  horizontal  drive line  2 which is connected both to the gate of the FET and  the  capacitively  coupled  control  electrode.          This permits a relatively high voltage read out signal to be provided on the horizontal drive line 2  without subjecting  the  line  to  an  excessive total voltage swing.

Abstract: The present invention relates to a method and apparatus for providing carrier frequency offset compensation in a time division multiple access (TDMA) communication system (100). In this effort a TDMA receiver (105, 107, 109, 111) is adapted to receive, via a transmission channel, a transmitted signal burst which includes a synchronization signal pattern, a message signal portion and at least one known portion, in a TDMA time slot. Initially, a phase error at that portion of the received signal which corresponds to the known portion of the transmitted signal is determined. Thereafter, various received signal parameters are adjusted in order to eliminate the phase error and thereby compensate for any carrier frequency offsets.

Title: High resolution acoustic pulse-echo ranging system
Inventor: PANTON STANLEY
IPC: G01S7/524
Filed: 1993-10-13
Granted: 1995-10-24
Abstract: The  uncertainty  inherent  in  high-resolution acoustic pulse-echo distance measuring systems which depend on threshold detection is overcome by transmitting a multi-cycle shot of acoustic energy having a sharply peaked amplitude profile, and locating the peak amplitude of a received echo.  The peaked amplitude is achieved by timing the duration of energization of a transducer producing the shot  so  that  energization  is  terminated  before  the amplitude of oscillation of the transducer has reached a maximum.  This produces a shot which has a definite largest cycle,  which should  in turn produce an echo having a definite largest cycle.

Title: Amplification of target nucleic acids using gap filling ligase chain reaction
Inventor: BIRKENMEYER LARRY G
IPC: C12Q1/68
Filed: 1992-06-26
Granted: 2004-08-24
Abstract: An improved "gap filling" embodiment of the Ligase Chain Reaction (LCR) is described. Gap filling LCR is LCR  wherein at least one of the probes is recessed so that a gap is formed between the adjacent probes when they are hybridized to target.   The gap is filled using polymerase and deoxyribonucleotide triphosphates before ligation of the probes together. There are single and double gap versions, depending on whether one or two probes are recessed and require filling before ligation. The improve-ment resides in selecting and using target sequences such that only a single type, or two types, of deoxyribonucleotide triphos-phate(s) are required to fill double gaps each being 1-10 bases in length, preferably 1-3 bases. Probes having specific sequences are claimed for a number of pathogens.
