Abstract: ABSTRACT             A movable door incorporates a proximity detection system for sensing obstructions in the path of the door. The system comprises an array of transmitter/receiver pairs (21, 22 and 23), each pair comprising a transmitter (1) for transmitting an energy pulse, a receiver (2) located adjacent the transmitter and directed to to receive any reflected transmitter pulses, and a shielding (3) for shielding the receiver (2) from receiving energy pulses directly from the transmitter (1). At least two transmitter/receiver pairs (21, 23) are mounted on a leading edge or face of the door (12) to transmit energy pulses in a direction which is not at right angles to the leading surface or edge of the door, to monitor for obstructions in the path of the door (12). Another two transmitter/receiver pairs (26 and 28) are mounted on the leading edge or surface of the door (12) to transmit energy pulses at right angles to the surface or edge of the door (12). One of the latter two receiver pair (26) has a different response to the other pair (27) so that when the door (12) approaches a stationary object the one pair (26) detects the object ahead of the other pair (27).          Means are provided to respond to the output of the one pair (26) indicating the detection of an object to inhibit the output of the other pair (27).

Title: Scheme for rapid adjustment of network impedance
Inventor: VITHAYATHIL JOHN J
IPC: G05F1/70
Filed: 1987-01-08
Granted: 1993-01-12
Abstract: ABSTRACT OF THE DISCLOSURE          A static controlled reactance device is inserted in series with an AC electric power transmission line to adjust its transfer impedance.  An inductor (reactor) is serially  connected   with   two   back-to-back   connected thyristors which control the conduction period and hence the  effective  reactance  of  the  inductor.   Additional reactive  elements  are  provided  in  parallel  with  the thyristor controlled reactor to filter  harmonics  and to obtain    required    range    of    variable    reactance.          Alternatively,  the  static  controlled  reactance  device discussed above may be connected to the secondary winding of  a  series  transformer  having  its  primary  winding connected in series to the transmission line.  In a three phase transmission system, the controlled reactance device may be connected in delta configuration on the secondary side  of  the  series  transformer  to  eliminate  triplen harmonics.  With series transformer, secondary windings to which the  controlled  reactances  are  connected  could  be arranged  for  six-pulse  or  twelve-pulse  operation.   High degree  of  controllability  of  power  or  current  on  a transmission line can be achieved by the application of the device.   The device could be used  to overcome  some problems of series capacitor compensation of transmission systems permitting levels of series capacitor compensation higher   than  what   is  currently  used  or  considered practicable.   With  high  levels  of  series  capacitor compensation,  the   static   controlled   reactance   of relatively small size could be made the dominant transfer impedance of even long distance transmission system.  The device could be applied to effect improvement in AC power transmission  practice  in  terms  of  increase  in transfer capability,   better   transient   and dynamic   stability performance,  improved  damping  of  unwanted oscillations, control of unscheduled powerflow on transmission lines and reduction in transmission losses.

Title: Probability estimation based on decision history
Inventor: PENNEBAKER WILLIAM B
IPC: H03M7/40
Filed: 1987-08-07
Granted: 1991-11-05
Abstract: PROBABILITY ESTIMATION BASED ON DECISION HISTORY          ABSTRACT OF THE DISCLOSURE            Apparatus and method for adapting the estimated probability of either the the less likely or more likely outcome (event) of a binary decision in a sequence of binary decisions in-volves the up-dating of the estimated probability in response to the renormalization of an augend A. The augend A changes value with each binary decision, the size of the change de-pending on which of the binary events has occurred as input.          Re-normalization of A occurs when the A value becomes less than a prescribed minimum value AMIN. According to the in-vention, there may be differing contexts in which binary de-cisions  may  occur,  each  context  having  a  corresponding estimated probability value which is up-dated with binary decisions in the respective context. Also according to the invention, there may be one or more possible next values for an estimated probability in response to a given binary deci-sion event.  The selection of one of multiple possible next values in response to a given binary decision event is pref-erably determined based on a renormalization  correlation count.

Title: Method to quantify thermal dissipative mechanisms in biomaterials
Inventor: BOWMAN HARRY F
IPC: G01N25/18
Filed: 1987-12-30
Granted: 1993-04-06
Abstract: Abstract of the Invention A method for determining the properties of a medium by activating temperature changing means to change the temperature of the medium from a first unperturbed temperature to a second different temperature during a first time period and permitting the temperature to relax to a final unperturbed temperature during a second time period.  In a particular embodiment, for example, the intrinsic thermal conductivity and diffusivity of the medium are calculated during a selected portion of the first time period assuming an arbitrary value for the perfusion, and the perfusion of the medium is calculated during a selected portion of the second time period using the calculated intrinsic thermal conductivity and diffusivity.  The calculated perfusion is then used to recalculate the intrinsic thermal conductivity and diffusivity during the selected portion of the first time period and the perfusion is then recalculated using such recalculated intrinsic thermal conductivity and diffusivity.  The recalculation steps are repeated until each of the recalculated values converge to a substantially non-changing value.

Title: Methods and compositions for tenderizing and upgrading the sensory qualities of red meat
Inventor: HENDRICKS DELOY G
IPC: A23L13/00
Filed: 1988-03-17
Granted: 1993-03-16
Abstract: ABSTRACT    The present invention relates to methods, compositions, and apparatus for treating and upgrading the tenderness and sensory qualities of fresh red meats.  The present invention provides a mechanism whereby low grades of meat may be made tender,   flavorful,     and  juicy  without  significantly increasing saturated fat content.   This is accomplished by injecting  the  meat  with  appropriate  injectates.    Such injectates may include unsaturated vegetable fats such as corn oil, water,  and even beef tallow or other saturated fats.  It is presently preferred to include a binder in the injectate such that a substantial portion of the injectate is retained within the meat even after cooking.  Failure to provide a binder  often  results  in a  drier  tasting meat product.    The present invention also teaches the construction of an apparatus which allows injection in a sanitary manner.          Additionally,  injection can be accomplished such that the meat product may have the appearance of natural marbling.     PAT/11093-la

Title: Graphics input tablet
Inventor: PASCUAL RAFAEL
IPC: G06F3/033
Filed: 1988-04-14
Granted: 1992-03-10
Abstract: ABSTRACT                GRAPHICS INPUT TABLET      A graphics input tablet has a conductive layer and a resistive layer with contacts (16,17,23,24) arranged one along each edge of the resistive layer. The conductive layer is held at a negative potential relative to the resistive layer so current flows in each contact when localised pressure is applied to a region of the tablet (20) to bring the layers into electrical contact. The currents vary with both posi-tion and magnitude of the localised pressure. The position of the pressure is detected from the relative currents in opposed contacts and the magnitude of the pressure is detected from the total current in the contacts. The currents are measured by current sense amplifiers and processed in a computer. Analogue front-end processing of the currents is also possible.
