Patent CA-1275262-C (CA)
Title: Filters
Inventor: CLARKE DAVID J
IPC: B01D33/03
Filed: 1986-06-12
Granted: 1990-10-16
Abstract: ABSTRACT      A filter which is particularly useful with biological material is formed of porous piezoelectric material such as PZT or Polyvinylidene fluride.  By an application of a voltage to the piezoelectric material, the filter body is caused to vibrate so as to inhibit fouling. In a modification, the piezoelectric material is not itself porous but is bonded to a filter membrane such that vibrations of the piezoelectric material are transmitted to the membrane. Through suitable control of the vibration, the selectivity of the filter can be controlled. In other modifications the vibratory movement of the filter membrane can be produced in other ways such as electro-mechanically.

Title: Circuit for eyesight protection in a television set
Inventor: KIM EUI DUK
IPC: H04N5/64
Filed: 1986-09-11
Granted: 1989-12-05
Abstract: ABSTRACT This disclosure depicts a circuit for protecting eyesight from the screen of a TV set. An infrared transmitter is provided on a side of the front of the TV set so that pulse signals therefrom after reflecting upon a viewer within a predetermined distance are received on a receiving-amplifying portion for remote control which is already installed in the TV set. A monostable multivibrator has an input to which is applied the pulse output signal from the remote control receiving-amplifying portion thereto. A delay circuit portion has an input operatively connected to the output of the monostable circuit portion. The monostable multivibrator produces higher level signals on the output thereof when the higher level signals are applied on its input over a predetermined time and produces lower level signals otherwise. A video amplifier driving circuit portion for controlling the "ON" and "OFF" of video amplifier which has an input operatively connected to the output of the delay circuit portion and also has an output.

Abstract: Abstract of the Disclosure A system for controlling access and transmission timing of communication in a repeating sequence over a network between nodes of one or more terminals, such as in a local area network. Each node in the network is equipped to recognize the presence of boundaries in the transmissions of messages by all nodes in the network. Each node is assigned a place in the list of all the nodes on the network and is controlled by a local timing system to be able to transmit over the network only after the node next preceding it in the list has transmitted. This recognition is accomplished by counting the message boundaries on the network and comparing the count against the list of nodes in the network. Each node will transmit during its time a message of variable length, up to a maximum, but never lass than a minimum that identifies its presence in the network. The system has the capability to recognize a missing node and a jammed network by timing the intervals between messages and comparing these against the maximum allowable transmission times. The system utilizes a very small minimum transmission time so that great efficiency is achieved. The intervals between node transmission time is set to be just larger than the maximum predictable network delays. This achieves predictability in network operation that allows each node to use internally generated timing to identify the cyclical network operation, while achieving high efficiency in network operation and accommodating real time transmission needs.

Title: Simple-code encoder/decoder
Inventor: LABARGE STEVEN B
IPC: H03M5/18
Filed: 1988-05-31
Granted: 1991-09-17
Abstract: Abstract of the Disclosure A Simple Code encoder/decoder converts a ternary, or bipolar, signal having a strong clock component into a binary signal while maintaining the strong clock component for processing with digital equipment.  The Simple Code is high for each positive value of the bipolar signal, low for each negative value of the bipolar signal, and alternates high/low for each zero value of the bipolar signal.  The encoder uses an extractor circuit to generate a +PULSE signal, a -PULSE signal and a CLOCK signal from the bipolar signal.  The +PULSE and CLOCK signals are combined to produce an intermediate binary signal, and the intermediate binary signal is combined with the -PULSE signal to produce the Simple Code binary signal.  The decoder extracts the CLOCK signal from the Simple Code binary signal and uses the CLOCK signal to generate positive and negative pulse signals corresponding to the highs and lows of the binary signal of a duration equal to the period of the CLOCK signal.  The positive and negative pulse signals are combined to produce the original bipolar signal.
