Patent CA-2149214-A1 (CA)
Title: Apparatus for and method of speech digitizing
Inventor: DENT PAUL W
IPC: G10L19/00
Filed: 1994-09-13
Abstract: ABSTRACT OF THE DISCLOSURE    A speech encoder converts analog speech signals into a stream of binary coded speech samples.  A circuit for performing analog to digital conversion compares an input speech signal with a signal from a digital integrator.  Based on the comparison, a series of decisions are registered which indicate a step sign of the input signal.  A syllabic filter generates a step magnitude according to the registered decisions.  The step sign and step magnitude are combined providing a sign/magnitude representation of the input signal.  When the sign/magnitude is integrated digitally in a decimation filter a digital representation of the analog signal is formed.  A speech decoder, the antithesis of the encoder, converts binary coded speech samples into an analog waveform in a manner opposite to the A/D conversion method.

Patent CA-2150592-A1 (CA)
Title: Visual display system having low energy data storage subsystem with data compression capabilities, and method for operating same
Inventor: MITAL AMIT
IPC: H04N7/26
Filed: 1995-05-31
Abstract: A visual display system for use in computers includes a frame buffer for holding visual information data in a particular format for ready input to a visual display device. The system also includes a compressed frame buffer for storing the visual information data in a compressed format which can be rapidly decompressed in real-time and used in the visual display device. The data is compressed by a microprocessor during idle times and decompressed by a decompression circuit on the fly. In some circumstances, the power consumed by compressing and then repeatedly handling the compressed data is less than the power used to repeatedly handle the full uncompressed data set. The visual display system analyzes the visual information data and determines whether compression would help save energy. In the event that the handling of compressed data saves energy, the visual display system will use the compressed data set until the information is changed or updated. In this manner, the visual display system reduces power consumption which helps improve battery life in portable computers.          A method for operating a visual display system using this energy saving compression technique is also described.

Title: Method of controlling a telecommunications network
Inventor: CRABTREE IAN BARRY
IPC: H04Q3/00
Filed: 1994-03-23
Abstract: A method of controlling a telecommunications network in which local exchanges (1) are connected to a network of trunk exchanges (6) via one or more parent trunk exchanges (3, 4). The method provides a network traffic management system (NTMS) which detects focused overloads at parent trunk exchanges (3, 4) and, rather than applying call restriction to the parent trunk exchange (3, 4) itself, applies call restriction to one or more of the other trunk exchanges (6) in the network, known as far-end trunk exchanges. This arrangement can allow added flexibility in the way call restriction is applied. For instance, cases arise when certain routes (7) into a parent trunk exchange (3, 4) contribute more than others to a focused overload.      It may then be preferable to apply call restriction in relation to a route which is inversely proportional to that route's contribution to be focused overload.
Patent CA-2160352-A1 (CA)
Title: Ultra-wideband radar motion sensor
Inventor: MCEWAN THOMAS E
IPC: G01P13/00
Filed: 1994-04-08
Abstract: A motion sensor is based on ultra-wideband (UWB) radar.      UWB radar range is determined by a pulse-echo interval. For motion detection, the sensors operate by staring at a fixed ranged and then sensing any change in the averaged radar reflectivity at that range. A sampling gate is opened at a fixed delay after the emission of a transmit pulse. The resultant sampling gate output is averaged over repeated pulses. Changes in the averaged sampling gate output represent changes in the radar reflectivity at a particular range, and thus motion.

Filed: 1996-03-21
Abstract: Apparatus and methods are shown for controlling a weighing machine in which product is fed into one end a vibratable pan of a vibratory feeder and is discharged from the other end, for example into a weigh bucket. In a first embodiment, the amplitude of vibration of a pan is measured and is compared to adesired amplitude. The measured amplitude is compared to a desired amplitude, and the amplitude of vibration is adjusted by modifying an input signal to a vibrator attached to the pan until the measured amplitude equals the desired amplitude. In a second embodiment, a mechanism is included to stop the loading of product into a pan when a predetermined amount of product has been discharged from a pan into a weigh bucket, and the weight of product in the pan is monitored as additional product is discharged into the weigh bucket. Only a preselected additional weight of product is subsequently discharged into the weigh bucket. A third embodiment involves at least two pans arranged in series, and the weight of product in the downstream pan is determined and monitored. The measured weight is compared to a desired weight of product in the downstream pan, and the amplitude of vibration of the upstream pan is adjusted, as needed, in a closed-loop manner to feed more or less product into the downstream pan to establish and maintain the desired weight in the downstream pan.

Title: Available Bit Rate Scheduler
Inventor: RADHAKRISHNAN SIVAKUMAR
IPC: H04L47/6275
Filed: 1996-03-27
Abstract: An  available  bit  rate  scheduling method  and apparatus for asynchronous transfer mode communication of a plurality of cells over a network characterized by a system clock frequency f and an allowed cell rate ACR. Each cell belongs to an assigned virtual circuit communication channel which is defined by a set of negotiated traffic parameters.  The invention partitions the ACR's of the virtual circuits into a smaller subset of profiles/ subprofiles and conducts a deterministic search to service them.  The scheduler incorporates a profile generator for iteratively generating a number p of the profiles by (i) outputting a k*modulo 2ith one of the profiles during each kth iteration of the profile generator, where 1 ~ i ~ p and 1 ~ k ~ p-1; (ii) outputting a null profile during each 2pth one of the iterations; and,  (iii) dispatching the profiles from the profile generator to the profile queue such that a   particular   profile   is   dispatched   at   a   time T = To + (1/ACR) *f, where To is the dispatch time of a profile dispatched immediately prior to the particular profile.  A profile queue coupled to the profile generator receives and sequentially stores the generated profiles. A virtual  circuit  processor  sequentially  receives  the profiles from the profile queue and, for each one of the received profiles, dispatches to an output queue all virtual circuits which are characterized by the one received profile.
