Abstract: Railroad telemetry radios are tested by an automated method for in situ testing, so that only those units requiring adjustment and maintenance are removed. A multi-function test set is programmed to automate testing of the radios used in a telemetry system in conjunction with other test software embedded in the host telemetry devices. The radios contain both a transmitter and a receiver. Both are individually tested to verify proper performance. Receiver sensitivity testing of the radio is tested by bit error rate (BER) measurement with test software and a dedicated BER modulator. A known low amplitude message comprised of a short pseudorandom pattern continuously repeated by the test set BER modulator is demodulated by the radio receiver. The test software processes the received data and counts the number of errorless messages received over a specific period of time. The receiver sensitivity is known to be acceptable if the number of correct messages received is higher than a predetermined minimum value. The transmitter performance is tested by measuring radio frequency (RF) carrier frequency, modulation frequency, deviation and RF output power. The test set is programmed to automatically measure these parameters, determine whether they meet minimum requirements, prompt the technician as to pass/fail status, and optionally display measured test data for use in radio repair, if required, or for statistical purposes.

Title: Air-conditioning system for below-deck areas of a passenger aircraft
Inventor: BUCHHOLZ UWE
IPC: B64C13/08
Filed: 2000-06-16
Granted: 2007-12-04
Abstract: An aircraft air-conditioning system provides ventilation, air--conditioning and fire protection for a below-deck stairwell and cargo hold that may be equipped with passenger sleeping compartment containers. An air mixing unit mixes fresh air and recycled air to supply mixed air through a first supply air main line and a supply air unit into the freight hold, and through a second supply air main line into the stairwell. A trimming air unit provides hot bleed air from the aircraft engines into the mixed air supplied through the first and second supply air main lines. An exhaust air line extracts exhaust air from the freight hold, while an exhaust air supplemental line extracts exhaust air from the stairwell, both of which are connected to an exhaust air main line with an exhaust air ventilator that blows the exhaust air overboard. A bypass line provides bypass air if needed for the demands of the ventilator. Regulating valves and non-return flap valves in the supply air line and in the exhaust air line regu-late the flow of air and prevent back-flow. Temperature sensors are connected to a controller that regulates the temperature of the mixed supply air to achieve a comfortable temperature in the freight hold and in the stairwell. In the event of fire, the air valves are closed, to seal-off the freight hold and prevent the spread of smoke into the stairwell or other ventilated areas.

Abstract: Apparatus and methods are disclosed for simultaneously tracking multiple finger (202-204) and palm (206, 207) contacts as hands approach, touch, and slide across a proximity-sensing, compliant, and flexible multi-touch surface (2). The surface consists of compressible cushion (32), dielectric electrode (33), and circuitry layers. A simple proximity transduction circuit is placed under each electrode to maximize the signal-to-noise ratio and to reduce wiring complexity. Scanning and signal off-set removal on electrode array produces low-noise proximity images. Segmentation processing of each proximity image constructs a group of electrodes corresponding to each distinguishable contacts and extracts shape, position and surface proximity features for each group. Groups in successive images which correspond to the same hand contact are linked by a persistent path tracker (245) which also detects individual contact touchdown and liftoff. Classification of intuitive hand configurations and motions enables unprecedented integration of typing, resting, pointing, scrolling, 3D manipulation, and handwriting into a versatile, ergonomic computer input device.

Filed: 2001-06-12
Granted: 2008-10-28
Abstract: A fuel injection control system and method for delivering multiple fuel injections to a cylinder of an engine during a fuel injection event based upon engine operating conditions, the control system including an electronic controller coupled to an electronically controlled fuel injector, and a plurality of sensors coupled to the controller for inputting certain signals representative of certain engine operating conditions, the controller being operable to output a fuel injection signal to the fuel injector to deliver multiple fuel shots to the cylinder during a fuel injection event based upon the sensor signals. The controller also determines when an active fuel injection waveform should transition to another waveform based on fuel and engine speed changes. The controller sets single check fuel and engine speed hysteresis values, and determines fuel and engine speed changes. If both the fuel and engine speed changes are greater than the respective hysteresis values, the active waveform is changed to a potential waveform, which is found in a lookup table or map. The waveform will also change if the fuel change is continuously greater than a loop fuel hysteresis value, which value is larger than the single check fuel hysteresis value, for longer than a selected period of time such as approximately 3.8 seconds.

Title: Method and arrangement for synchronization of base stations in a mobile communications network
Inventor: HEITMANN JURGEN
IPC: H04M7/00
Filed: 2000-09-07
Granted: 2005-04-12
Abstract: For synchronization of base stations (BS1, BS2), in particular for the purpose of a seamless handover, time information (ZI1, ZI2) is transmitted - possibly on request - to the base stations (BS1, BS2) from a time information server (VE) via a local area network (LAN).      Since base stations (BS1, BS2) which are involved in a seamless handover are generally adjacent, and the respective propagation times and/or propagation time fluctuations of time information (ZI1, ZI2) differ only slightly in the local area network (LAN) between the time information server (VE) and the base station when the base stations are adjacent, the invention allows high accurate synchronization to be achieved, especially for a seamless handover.

Abstract: A method for transmitting control data on a downlink and/or uplink channel in a base station and/or mobile station in a mobile communication system. In one embodiment, the base station determines whether there is downlink channel data to transmit to a mobile station. If there is no data to be transmitted over the downlink channel for a predetermined time period, the base station drives a random gating position selector to determine a random gating slot position, gates on the control data at the determined slot position, and gates off the control data at other slot positions. The random position selector determines the gating slot position by calculating a value x by multiplying a system frame number (SFN) of a received signal by a specific integer; selecting n bits starting from a position which is at an x-chip distance from the start point of a scrambling code, which has a period equal to one frame, before a plurality of gating durations used in generating a downlink signal; and determining a gating slot position of a corresponding gating slot group by performing a modulo operation on the selected n bits, where the module operation is by the number of slots in a gating slot group.

Granted: 2007-08-14
Abstract: L'invention concerne un rouleau porteur en auge (62) qui permet de supporter une bande transporteuse d'un système transporteur à bande en auge. Le rouleau porteur en auge (62) comprend deux rouleaux intermédiaires (64, 66) espacés et deux rouleaux en auge inclinés (40, 42). Les deux rouleaux intermédiaires (64, 66) sont solidaires d'une patte de fixation pivotante (58) et leurs axes de rotation sont éloignés l'un de l'autre d'une distance de liaison. Les rouleaux intermédiaires (64, 66) sont choisis de façon qu'ils aient chacun le même diamètre extérieur, et leurs dimensions sont choisies de façon à avoir un diamètre extérieur supérieur à celui de chacun des rouleaux en auge inclinés (40, 42). L'accroissement du diamètre extérieur des rouleaux intermédiaires (64, 66) par rapport au diamètre extérieur des rouleaux en auge inclinés (40, 42) réduit la résistance à l'indentation au niveau du rouleau porteur en auge (62). Ce dernier comporte en outre un mécanisme de limitation pivotant (36, 68) qui limite la rotation dans le sens et dans le sens contraire des aiguilles d'une montre des pattes de fixation pivotantes (58) utilisées pour porter les deux rouleaux intermédiaires (64, 66).
