Title: Technique for cancelling signal dispersion in communications systems
Inventor: AMRANY DANIEL
IPC: H04N5/21
Filed: 1993-02-24
Granted: 1998-10-06
Abstract: A signal dispersion cancellation structure receives incoming signal samples at an incoming rate, stores these samples in a first memory and then writes these samples at a submultiple of the incoming rate into a plurality of second memories. Each second memory is associated with a finite impulse response (FIR) filter and the second memory samples are coupled to the associated FIR filter at the incoming rate. Advantageously, apparatus is also provided which enables any sample in a second memory to be provided to the associated FIR filter and outputted therefrom at a time related to the position of any signal dispersion.

Title: Double piston propulsion unit
Inventor: CLARK ROBERT OWEN
IPC: F41A/
Filed: 1991-09-26
Granted: 2001-05-01
Abstract: A double piston propulsion unit for a recoilless mass/countermass projectile launcher comprises two hollow cylindrical pistons (22, 23) arranged in a back-to-back relationship with closed outer ends and open inner ends, the open inner ends being joined together by a circumferential rupturable connecting means so that the pistons form a vessel in which a propellant charge (34) is enclosed. In operation, the unit is slideably located inside the open-ende launch tube (1) of the projectile launcher at its mid-point. The propellant when initiated causes a build up of propellant gases inside the vessel and when the gas pressure reaches a pre-determined value the connecting means fails in tension and the pistons (22, 23) are propelled in opposite directions. The tensile and compressive force experienced by the pistons (22, 23) during the firing of the unit are substantially decreased compared to known units, so that relatively lightweight pistons (22, 23) can be employed.

Title: Prioritization between handoff and new call requests in a cellular communications system
Inventor: BODIN STIG ROLAND
IPC: H04W28/16
Filed: 1992-12-08
Granted: 2002-08-20
Abstract: A method and system for ensuring that handoff requests take priority over new cell requests to engage voice channels assigned to a particular target cell are provided. A certain number of channels are reserved for handoff requests. However, if no channels, reserved or unreserved, are available, handoff requests to a particular target cell are stored in a corresponding queue for a predetermined period of time. Thus, when voice channels become available, they are seized in order to satisfy the handoff requests stored in that queue. If the handoff queue is empty, new call requests to a target cell may be assigned to available voice channels.

Abstract: A method and apparatus for electronically performing bookkeeping upon a plurality of accounting journal entries having at least one account number and at least one data component associated with each account number.  A chart of accounts having account numbers and opening balances associated with the plurality of journal entries is read electronically.  A set of account-section numbers is then created for each account number.          The journal entries are electronically read and one of the account-section numbers is assigned to each account number.  The assigned account-section numbers and associated data components are then sorted in a predetermined order.  A design for the predetermined order is identified and compared with stored design records to see if such a design already exists.  If not, the new design is stored.  If so, the associated data components are added to the accumulated total for each account-section number.     A tally representing the number of account-section numbers is increased by one and an entry number is added to a list for the particular design record.  The process is then repeated for each journal entry.

Granted: 1998-11-03
Abstract: A control circuit for controlling the voltage supply  to  selected  ones  of  a  plurality  of  output terminals to which controllable devices are connected to  is  described.    The  control  circuit  comprises manually operable function switches which are connected to an integrated circuit providing output logic signals to feed an interlock circuit to select the operation of one or more of a plurality of high voltage electronic switching devices.   An interface circuit is connected between the switching devices and the interlock circuit to trigger the operation of selected switching devices to connect a high voltage supply to associated ones of the  output  terminals.    The  interface  circuit  also prevents feedback voltage surges from the one or more switching devices to protect electronic circuits in the control circuit.  An overcurrent protection circuit is connected  between  an  output  of  the  high  voltage electronic switching devices and the integrated circuit to disable the output logic signals and the interlock circuit to cut the high voltage supply at the output terminals  when  the  current  exceeds  a  predetermined reference value.

Title: Retractable-needle cannula insertion set with refinements to better control leakage, retraction speed, and reuse
Inventor: COVER WALTER E
IPC: A61M5/32
Filed: 1994-11-14
Granted: 1999-06-15
Abstract: Leakage of blood from the insertion set, during and after safety-needle retraction, is suppressed by components that receive and retain flash blood for viewing -- notwithstanding forces developed within the device in retraction.  One preferred such system includes a flash chamber that moves with the retracting needle, within a hollow handle, carrying a relatively high flow-impedance element which allows air exhaust from the chamber into the handle to admit flash blood -- but isolates blood in the chamber from retraction-generated increase in air pressure in the handle.  Energy-absorbing components control or compensate for retraction speed, to provide quiet smooth retraction -- while yet enabling use of ample retraction force to make retraction reliable.  Among several energy absorbing systems disclosed is a preferred one that includes a viscous material introduced within the hollow handle to damp the retracting motion; and an injection port to facilitate introduction of the viscous material.  Needle reuse, and concomitant risk of spreading disease, are avoided through components that deter needle redeployment -- by deterring access to or forward motion of the needle, or trigger reengagement.

Abstract: Seismic data from co-located sensors of different genera are formatted into common velocity-receiver gathers and common pressure receiver gathers. A first ratio between the velocity signature amplitudes and the pressure signature amplitudes is measured within a fixed analysis window. A second ratio is measured between the pressure and velocity signatures for a weighting-zone window of limited extent. The first and second ratios are combined to form an equalization operator. The pressure and velocity signatures from within the weighting zone window are combined in the presence of the equalization operator to define a transient-free time-scale datum.
