Title: Multi-frequency photoelectric detection system
Inventor: MATHEWS PAUL
IPC: G01S17/931
Filed: 1998-07-22
Granted: 2004-10-12
Abstract: Collision avoidance apparatus (28, 30) is mounted on a host vehicle (20) to detect the presence of an adjacent vehicle (22) within a monitored zone (24, 26). A sensor module (30) includes a plurality of discrete sensor systems for monitoring unique portions of the monitored zone (24, 26), each of which comprises an emitter (52) emitting a fixed frequency modulated beam (58) of light energy (54) with a predetermined burst length into its unique portion of the monitored zone (24, 26), and a receiver (68) having a field of view (62), substantially aligned with the emitted beam (58) to produce a fixed optical overlap area (A), and for sensing light energy (66) and generating a received signal. A frequency generator (48) produces two or more predetermined different fixed frequencies for use by the emitter (52) to emit beams (58) at each frequency. A phase shifter (70) produces a phase shifted reference signal with a different predetermined phase delay relationship to each fixed frequency. A mixer (72) mixes each received signal and each phase shifted reference signal to produce demodulation signals from for each frequency. A processor (40) receives and processes accoupled logic level detection signals generated by a limiter amplifier (76) for each discrete sensor system at each of the fixed frequenciesto determine the presence of a vehicle (22) in the monitored zone (24, 26). The fixed frequency and the predetermined phase delay are chosen to produce a null received signal resulting from reflections of the emitted beam from uniformly distributed atmospheric backscatter within the optical overlap area (A).

Title: Dispositif et procede de commande de puissance, servant a commander un canal commun de liaison de retour dans un systeme de communication mobile
Inventor: KIM YOUNG-KY
IPC: H04B7/005
Filed: 1999-07-13
Granted: 2003-09-23
Abstract: L'invention concerne un procédé de commande de la puissance de transmission d'un canal commun de retour, destiné à une station mobile d'un système de communication CDMA. Selon ledit procédé, la station mobile émet un signal de préambule à des moments prédéterminés avec une puissance de transmission croissante. Dès réception d'un signal d'accusé de réception en provenance d'une station de base, la station mobile accède au canal commun de retour. Afin d'éviter que plusieurs stations mobiles ne génèrent simultanément des transmissions de plus en plus puissantes et perturbatrices, le procédé génère deux signaux de commande de la puissance de transmission: l'un basé sur l'intensité mesurée du signal reçu de la station de base, et l'autre basé sur une valeur cumulée des instructions de commande de puissance transmises par la station de base. Ces deux signaux sont cumulés et utilisés pour commander le signal de préambule.

Title: Packet scheduling in a communication network with statistical multiplexing of service classes
Inventor: ELWALID ANWAR
IPC: H04L12/56
Filed: 2000-02-28
Granted: 2004-07-06
Abstract: This Generalized Processor Sharing (GPS) is the basis for the packet scheduler of choice in IP routers and ATM switches of the future. The currently accepted approach for the design of GPS schedulers is based on deterministic QoS guarantees, which, it is generally accepted, is overly conservative and leads to limitations on capacity. To address this problem we develop a framework for GPS scheduling which is based on statistical QoS guarantees and statistical multiplexing. We give the design of GPS weights which maximize the coverage of operating points, and also the design of the connection admission control (CAC). The general framework is end-to-end, with two heterogeneous QoS classes coexisting with a third, best effort class. Each QoS  class has a specified delay bound together with a bound on the probability of its violation. An important objective is to maximize the bandwidth available to best effort traffic while just satisfying the guarantees of the QoS classes. To this end, we consider output regulated GPS scheduling which has the additional feature of limiting each connection's share of the bandwidth to a specified value, a design parameter which is determined by our analysis. The sources are subject to standard dual leaky bucket regulation.  For the design of the GPS weights we give procedures based on two key concepts, the realizable set and the critical weights. The realizable set is the union of all admissible sets of connections of both classes over all weights. One of the main contributions is a pragmatic design process by which most of the realizable set is realized by only two critical weights. In the benign case, the system is "effectively homogeneous"  and a single GPS weight suffices, while in the complementary "effectively non-homogeneous" case it is necessary to switch between the critical weights. The numerical results, which are for a single node with a wide range of traffic and QoS parameters, validate the design procedure and also show that there are substantial capacity gains from statistical multiplexing.

Abstract: The friction drive system (10) for printing, plotting or cutting graphic images on strip material (12) includes a feedback for a drive motor (40) driving a plurality of friction wheels (34, 36) for advancing strip material (12) in a longitudinal direction. The feedback signal comprises a short-term response component and a long-term response component to accurately pinpoint the exact longitudinal location of the strip material (12). The short-term response component is generated by comparing a motor encoder signal from a motor encoder (44) secured to the drive motor (40) with a commanded longitudinal position of the strip material (12) and passing the resultant differential error signal through an all pass filter (78). The long-term response component is generated by comparing a detecting encoder signal from a detecting encoder (54) secured to a device detecting the actual longitudinal position of the strip material (12) with the commanded longitudinal position of the strip material (12) and passing the differential error signal through a low pass filter (76).

If the estimated cooling water temperature is lower than or equal to the determination threshold, it is determined that the thermostat is normal.
