Patent CA-2079502-A1 (CA)
Title: Spectrally efficient broadband transmission system
Inventor: HANSEN DAVID E
IPC: H04L12/28
Filed: 1992-09-30
Abstract: ABSTRACT           A  baseband  signal  is  spectrally  efficiently transmitted on a broadhand transmission medium by inserting gaps in packets of digital data transmitted in a modulated first radio frequency carrier.  The transmitted packets of data are received by demodulating the modulated first radio frequency  carrier,  and  the  gap  is monitored  for  the presence of digital data thus indicating a collision of simultaneously transmitted packets of digital data.  A seed of arbitrary digital bits are used in scrambling each packet of digital data and is transmitted with the packet of  data  for  use  in  descrambling  the  data.     In retransmitting the packet of data the seed is included. The originally transmitting node receives the retransmitted packet  and  compares  the  retransmitted  seed  with  the originally transmitted seed  for detecting  an error  in retransmission.

Title: Method for receiving a communication after initiating a ptt
Inventor: SASUTA MICHAEL D
IPC: H04W84/08
Filed: 1992-10-20
Abstract: A Method For Receiving A Communication After Initiating a PTT                    Abstract of the Disclosure A communication unit that is registered in a trunked communication system can continue to receive a communication from a first communication unit after initiating a push-to-talk request while the first communication unit is transmitting voice data in the following manner. Having allocated a communication resource to a group of communication units and while processing a request to communicate for the first communication unit, a communication resource allocator receives a request to communicate from a second communication unit to produce a new request to communicate. The communication resource allocator stores the new request to communicate and transmits a response to the second communication unit such that the second communication unit can continue to receive the remainder of the communication from the first communication unit. Once the first communication unit has stopped transmitting its communication, the communication resource allocator retrieves the stored communication request based upon a predetermined retrieval pattern.

Patent CA-2091154-A1 (CA)
Inventor: JOHNSON HAROLD L JR
IPC: H02J1/00
Filed: 1993-03-05
Abstract: An apparatus and method for load voltage compensation. This involves increasing the length of time voltage is applied to electrical components, e.g., solenoid valves, in direct proportion to the number of electrical components electrically activated to compensate for the voltage loss in the control wires leading to the electrical components. The area of compensated pulse is then equal to the area of uncompensated pulse in order to compensate for the voltage drop. The load is anticipated prior to voltage application by summing the number of electrical components and associated loads selected and applying voltage for a period of time directly proportional thereto.

Title: User interface having simulated devices
Inventor: WARD JEAN R
IPC: G06F3/038
Filed: 1991-06-20
Abstract: A computer system having a digitizing tablet overlaying the display screen. The tablet serves as a user's primary input device.  Various features of the system make it possible for the user to run and interact with standard programs designed for keystroke and mouse input and not designed for use with a tablet. In addition to the main processor, on which the user's programs are executed, there is an interface processor. In addition to a standard display buffer, there is an ink plane buffer for interface display data that is combined with the data from the standard display buffer on a pixel-by-pixel basis according to data from a mask plane buffer. The interface processor manages input from the tablet, presents feedback to the user by means of the ink and mask planes, and provides keystroke and mouse data to the main processor as if from a standard keyboard controller. The interface processor presents the user with a collection of simulated devices, including standard devices such as a keyboard and a mouse. A nonstandard simulated device performs character recognition, permitting handwritten characters to be used for program input. During interaction with one of the user's programs, the user can activate and deactivate simulated devices (by removing them from and returning them to a device tray) and can make adjustments in their operation and location on the screen.

Patent CA-2109755-A1 (CA)
Inventor: FRENCH JOHN B
IPC: H03F1/52
Filed: 1993-11-23
Abstract: An improved composite bridge amplifier having four semiconductor output transistors in a bridge configuration. The control terminals (gates or bases) of the transistors are controlled by an input signal which is amplified in a phase sputter and voltage gain stage and then applied to the control terminals. The output terminals of the transistors receive a power signal which varies with the input signal at a level sufficient to maintain headroom above the output signal but to reduce power dissipation in the transistors. The power signal is produced by a switch connected between a floating power supply and a filter and operated at e.g. 200 kHz. The switch is operated by a pulse width modulated (pwm) signal derived from the absolute value of the input signal. The improved composite bridge amplifier further includes a proportional integral controller coupled between the output of the filter and the pulse width modulator to provide closed loop feedback.      The output of the filter is aligned with the input signal by a phase shifter which is connected to the proportional integral controller.   Because the phase shifter eliminates the need for a time delay in the input signal (i.e. audio) path, high performance can be achieved with reduced cost. To further improve the performance of the amplifier at high frequencies, the improved amplifier includes a peak detector circuit for tracking a high frequency input signal and compensating the pwm signal. The improved amplifier also features thermal overload protection and output current overload protection circuits which protect the output stage by reducing the headroom. Because the protection circuits do not "clip" the output signal, the effect to the listener is minimized.

Title: Method and apparatus for ripening fruit
Inventor: HARTLEY GERALD
IPC: F25D17/00
Filed: 1994-01-11
Abstract: In a banana ripening room, pallets of boxes of fruit are stacked in individual locations defined by a support structure, in two spaced apart rows separated by an aisle, and in two superimposed tires. The aisle defines a volume into which air is introduced under pressure by fans in an overhead space separated from the room by a false celing.          All the gaps between adjacent pallets and structural members are sealed by rubber flaps, an efficient seal being obtained when boxes are used which are designed for use in pressurised ripening systems. The flaps are attached along one edge to structural members and free at their other edges to conform to the contours of the pallet loads, thereby ensuring that air can be cycled only through the pallet loads to lower pressure zones beyond the rows of pallets.     .

Title: Compressor unit
Inventor: BAUER HEINZ
IPC: B01D5/00
Filed: 1994-01-28
Abstract: A compressor unit that has a compressor component and a condensate filter that is used to precipitate water and oil condensed from a compressed gas stream. For the environmentally friendly disposal of the condensate, a filter device containing a filter material is arranged so that a warm air stream entering the filter device after passing through the condensate filter condenses the water in the filtrate stream. The condensate is soaked up in the filter device by the filter material and, with the help of the air stream, which can be the warmed outgoing air of a cooling device of the compressor component, the water contained in the condensate is evaporated, while the oil-containing components of the condensate are adsorbed in the filter material for subsequent disposal. The filter material is preferably placed in the filter device in the form of filter elements arranged preferably in several rows behind one another at predetermined distances in the direction in which air flows through. The filter element can be designed as an osmotic filter cloth which is formed as tubes or it can be made of spiral-shaped, wound sheets of such filter material. Suitably, the filter device with the filter material contained in it is designedas a replaceable, disposable device, for example in the form of a module.
