Title: Aerial support platform mechanism with five axes of motion
Inventor: KNELLER PAUL
IPC: F16M13/00
Filed: 1995-08-30
Granted: 1999-03-23
Abstract: An aerial support platform is supported to extend below, and intermediate of, a pair of parallel cables mounted along respective opposite walls of a studio.  A carriage rides on each of the parallel cables, and another pair of cables extends to connect the pair of carriages.  A third carriage sits on the other pair of cables, and a series of further cables extend vertically from that carriage to the platform.  The pair of carriages positioned on the opposite walls of the studio are controlled to move in tandem, and the third carriage has controlled movement between those carriages.  The platform may be raised or lowered relative to the third carriage, and thus has three linear axes of motion.  The platform has two additional axes of motion, both rotational.  One is around a vertical axis and another is around an axis normal to the vertical axis. Cinematographic equipment may be fixed to the platform, which can then be oriented using a computer at a remote location.

Title: Vehicle transmission system with variable speed drive
Inventor: VLOCK ALEXANDER
IPC: B60W10/18
Filed: 1995-11-17
Granted: 1999-08-17
Abstract: A vehicle transmission system is described which employs a split power path design to achieve continuously variable speed ratios. A motor-generator unit is provided for converting a fraction of the input power into electrical power, and a second motor-generator and differential gear mechanism are employed to re-combine the two power components before transmitting the mechanical power through a gearbox. Electrical power dissipation means allows the transmission system to provide slippage when accelerating a load from rest, and it also assists in shifting and in braking. An electronic motor controller coordinates feedback signals from various sensors and controls the dynamic performance of the entire system. The motor-generators are integrated with the housing of the transmission and have water jackets to assist in heat dissipation. The motor-generator pair and the power dissipation elements are all cooled by a circulating fluid which transfers heat from these components to an external heat exchanger.

Patent CA-2164964-C (CA)
Inventor: DAVIDSON GRANT ALLEN
IPC: H04B14/06
Filed: 1994-07-14
Granted: 2005-10-11
Abstract: The invention rotates in general to low bit rate encoding and decoding of information such as audio information. More particularly, the invention relates to adaptive bit allocation and quantization of encoded information useful in high-quality low bit rate coding systems. In an encoder a hybrid of forward-adaptive and backward-adaptive allocation is used to adaptively quantize information and to prepare an encoded signal which requires minimal side information to convey explicit allocation information to a companion decoder. In a decoder, a hybrid allocation technique is used to obtain allocation information required to dequantize information from a received encoded signal.

Abstract: A very high speed counter system of operating at frequencies of up to around 800 MHz provides timing measurements with accuracies on the order of (1/f) seconds where f is the frequency of operation. The least significant bit of the counter operates at the given frequency of a first clock signal while the other higher order bits operate at a second clock signal where the second clock signal is one-half the frequency of the first clock signal and is inverted. Carry lookahead circuits connected between stages of the second counter operate in conjunction with the clocking scheme to produce a high speed and accurate counter.

Granted: 2001-05-22
Abstract: A cell-site base station apparatus comprises an array of diversity antennas for receiving multipath components of a mobile-transmitted signal. Receivers, connected to the antennas, produce strength indication signals and demodulated signals. For transmission of a control signal from the cell-site to a mobile station, a variable gain transmitter is coupled to oneof the antennas and the control signal is sent at a first power level. When a connection is established for the mobile station, the strength indication signals from the receivers are examined to detect a highest strength value and one of the antennas is selected at which the multipath component of the highest strength value is arriving. The transmitter is then switched to the selected antenna for transmitting traffic signals and the gain of the transmitter is set to a second power level lower than the first power level to compensate for the transmit diversity gain of the selected antenna.
