IPC: H03M13/41

Abstract: This invention teaches a method, and circuits that operate in accordance with the method, for decoding data received from a communications channel. The method includes the steps of: (a) receiving a modulated communications signal that conveys block encoded data having at least a data field and a syndrome data field; and (b) determining transition metrics and path metrics for the block encoded data. The step of determining path metrics includes a step of retaining path metrics only for a Maximum-Likelihood (ML) path and for a second best ML path. The method further includes a step of: (c) decoding the block encoded data by performing either a full or a partial traceback operation for both the ML path metrics and also for the second best ML path metrics. In a full traceback there is obtained from the ML path a first plurality of detected bits representing the data field, a second plurality of detected bits from the ML path representing the syndrome data field, a third plurality of detected bits from the second best ML path representing the data field, and a fourth plurality of detected bits from the second best ML path representing the syndrome data field. A next step (d) determines a syndrome from the first plurality of detected bits, and then compares the determined syndrome to the second plurality of detected bits. Upon a match a next step (e) outputs the first plurality of detected bits as a received frame of data. If the step of comparing the determined syndrome to the second plurality of detected bits does not indicate a match, the method instead: (f) determines a syndrome from the third plurality of detected bits; (g) compares the determined syndrome to the fourth plurality of detected bits and, upon a match, (h) outputs the third plurality of detected bits as a received frame of data.

Abstract: A vehicle security apparatus for use with a cable operated mechanism comprises a frame in which a latch member is movable in a guideway. The latch member is connected to the core of a Bowden cable which operates the bonnet release catch of the vehicle. A solenoid controlled plunger is operable selectively to lock the latch member. In this condition, the cable cannot be operated, so that an unauthorised person cannot easily gain access to the vehicle engine compartment. When the solenoid is actuated, normally when a vehicle alarm/immobiliser system is disarmed legitimately, the plunger retracts, freeing the latch member and allowing normal operation of the bonnet catch.

Abstract: In accordance with the present invention, a novel Time Division Multiple Access (TDMA) duplex radio communication system comprises an Interrogator which generates a first radio signal by modulating a first information signal onto a radio carrier signal. The Interrogator transmits the first radio signal to at least one remote Tag of the system. The remote Tag receives and processes the received first radio signal. The remote Tag then modulates a second information signal onto a second radio carrier signal to form a second modulated signal. This second modulated signal is then transmitted, in a time-slotted manner, back to the Interrogator. The remote Tag selects, or is instructed, how many times it should repetitively transmit the second modulated signal; and selects, or is instructed, over how many of the time slots following receipt of the first radio signal the remote Tag should repetitively transmit the second modulated signal. Other embodiments of this invention include the use of Modulated Backscatter to transmit the second modulated signal, and the use of homodyne detection to demodulate the second modulated signal. A Frequency Division Multiple Access (FDMA) duplex radio communication system embodiment utilizes multiple subcarrier frequencies and another embodiment combines the FDMA and the TDMA methods. A Code Division Multiple Access (CDMA) embodiment utilizes multiple spreading codes; in addition, another embodiment combines the CDMA and the TDMA methods. A novel method for power control of the tag, using modulated backscatter, is also disclosed. Finally, a method for the Interrogator to instruct the Tag to dynamically alter the data rate of the second information signal is also disclosed.

Abstract: A drilling tool, adapted to drill a wellbore in an earth formation, comprises a weight on bit equaliser shock sub. The weight on bit equaliser shock sub includes a precharged nitrogen chamber and additional chambers, the nitrogen in the nitrogen chamber adapted to telescopically open the equaliser shock sub during the drilling of the wellbore thereby maintaining a constant weight or force on the drill bit during the drilling operation. A force resultant from the pressurised nitrogen exists in the nitrogen chamber and additional forces resultant from a pressurised wellbore fluid exist in the additional chambers. The shock sub is specially designed in a particular manner to cause the sum of the force of the nitrogen in the nitrogen chamber and the additional forces of the wellbore fluid in the additional chambers to be equal solely to the force of the nitrogen in the nitrogen chamber. As a result, the weight or force on the drill bit is constant when the sum of the force in the nitrogen chamber and the additional forces in the additional chambers is equal solely to the force of the nitrogen in the nitrogen chamber. In a preferred, second embodiment, when the additional chambers include an atmospheric chamber, the weight or force on the drill bit is constant when the cross sectional area of the atmospheric chamber is equal to the cross sectional area of the nitrogen chamber. As a result, the only force on the drill bit during drilling is the force of the precharged nitrogen in the nitrogen chamber and consequently a constant weight or force on the drill bit is maintained during the drilling operation.

Abstract: The capacitance measurement involves a bridge (A) having reference and unknown capacitors, which is supplied at two first diagonal points with a periodic rectangular voltage with constant amplitude which switches between two signal levels. Only while the signal is at a second level, is the voltage difference at two second diagonal points of the bridge continually amplified in a synchronous amplifier (D) esp. a comparator. During the first voltage level, the synchronous amplifier outputs a predetermined potential. The amplified output signal is controlled by a regulator, esp. an integral regulator (E), to a target value which is determined by the time average of the output voltage of the amplifier when the bridge is balanced. The output voltage of the regulator is used via a counter coupling branch (G) and a balancing clamp circuit (C) to balance the bridge at the second diagonal points. The output voltage of the regulator is thus proportional to the capacitance or capacitance change of the unknown capacitor(s).

Abstract: The present invention is an apparatus, system, and method for converting point codes in a signal transfer point in a telecommunications signaling system. The STP converts point codes which designate the origination and destination signaling points for the message. The conversion is based on information defined by the messages, such as origination or destination information. The present invention creates a virtual signaling system which can be reconfigured at the STP by converting point codes, and thus, altering the identities of the signaling points. The present invention is also operable to convert circuit identification codes and transfer integrated services user part messages to a user part.

plate 2 and a rear side plate 3, which are arranged so
that a heat generating chamber 5 is formed between their
facing back surfaces and which are stored in a housing so
that heat emission chambers FW and RW are formed between
the side plates and the housing. The housing is formed
by a front housing having a tubular part 1c which extends
axially for storing the front and side plates radially
inwardly of the tubular part 1c and a rear housing 4.
Thus, sealing is necessary only at a location where the
front and rear housings 1 and 4 are connected with each
other. Thus, a very simple structure is sufficient for
preventing any leakage of the recirculated fluid.
