Patent NO-178250-C (NO)
Inventor: TOURTIER PHILIPPE
IPC: H04N19/00
Filed: 1990-10-15
Abstract: PCT No. PCT/FR90/00101 Sec. 371 Date Oct. 22, 1990 Sec. 102(e) Date Oct. 22, 1990 PCT Filed Feb. 13, 1990 PCT Pub. No. WO90/10353 PCT Pub. Date Sep. 7, 1990.The method of the present invention is directed to information compression which allows for compatible decoding of a group of television signals with increasing resolutions. According to the present invention, a first step, at the transmitter, involves strobing the space frequency band of the signal to be transmitted which has the highest resolution into adjacent subbands. Then, the signal with the highest resolution to be transmitted is independently coded in each subband. The subbands are then multiplexed by separating the coded signals in each subband by means of non-imitable synchronizing patterns. At the receiving decoder, the signals received relative to each subband are decoded only taking into consideration those which are necessary in order to reconstitute at least one member of a resolution group. The present invention finds particular application in the transmission system for high-definition TV images.

Title: Method and apparatus for limiting the utilization of a system bus with distributed controlled access for alleviating saturation
Inventor: BARLOW GEORGE J
IPC: G06F13/368
Filed: 1990-01-09
Granted: 1999-02-23
Abstract: A plurality of units which are coupled to transfer requests,  transfer  data  over  an  asynchronous  bus network during allocated bus transfer cycles.   The network has a tie-breaking bus priority network which is distributed to a common interface portion of each of the plurality of units and grants bus cycles and resolves simultaneous requests on a priority basis.  At least  one  unit  includes  bus  saturation  detection apparatus included within its common interface portion for monitoring bus activity over established intervals of time. The detection of the occurrence of at least one available cycle over the given interval of time signals that the bus network is not in a saturated state.   When the indicator specifies that the bus network is saturated,  the unit throttles down  its operation by increasing the amount of time between issuing data requests.  Throttling continues until the bus is no longer being saturated.

Inventor: DREYER VOLKER
IPC: G01F23/28
Filed: 1990-09-19
Granted: 1995-06-20
Abstract: The apparatus comprises at least two oscillating rods which are secured spaced from each other to a diaphragm, the edge of which is connected to a screw-in piece.  On the side of the diaphragm remote from the oscillating rods a clamping screw is fixedly connected to the diaphragm so that the clamping screw and diaphragm assume a position with respect to each other in which the axes of symmetry coincide.  The clamping screw is surrounded by a stack of annular piezoelectric elements, electrode rings and insulating rings.  The stack forms the excitation and receiving transducer of the apparatus.  The stack-shaped excitation and receiving transducer is clamped and secured between the diaphragm and a hexagonal nut. The stack bears on pressure studs which are arranged between a metal ring terminating the stack and the diaphragm. The clamping force is chosen so that the diaphragm is simultaneously concavely prestressed.  The excitation transducer stimulates the oscillating rods to oppositely directed oscillations at their natural resonant frequency transversely of their longitudinal axes. The receiving transducer detects a change of the oscillation behaviour of the oscillating rods and this is utilized to determine and/or monitor the predetermined level.  Both the change of the oscillating frequency and that of the oscillating amplitude of the oscillating rods may be utilized.

Title: Pin-fin heat sink including flow enhancement
Inventor: AZAR KAVEH
IPC: F28F1/12
Filed: 1992-08-25
Granted: 1995-02-14
Abstract: PIN FIN HEAT SINK INCLUDING FLOW ENHANCEMENT Abstract Heat dissipation performance of a pin fin heat sink is improved by utilizing a flow guide arrangement. Flow guide members are positioned relative to the outer rows of the pin fins and longitudinal to fluid flow through the pin fin field of the heat sink. A gap between a lower edge of each flow guide member and a base surface of the heat sink forms apertures allowing potentially stagnant fluid in an interior region of the pin fin field of the heat sink to communicate with fluid flowing around the exterior of the heat sink. This causes a so-called "pump" action in which the potentially stagnant fluid is drawn along with the fluid flowing around the exterior of the heat sink. (FIG. 5)
