Patent GB-2449470-B (GB)
Title: OFDM-MIMO radio frequency transmission system
Inventor: HAFFENDEN OLIVER PAUL
IPC: H04B7/04
Filed: 2007-05-23
Granted: 2011-06-29
Abstract: An OFDM-MIMO radio-frequency transmission system takes the form of a DVB-T system which is modified in that the phases of selected ones of the pilot signal transmissions, particularly the scattered pilots, are chosen or changed at the transmitters such that some of the corresponding pilot signal transmissions from the two (or more) MIMO transmitter stages are in the same phase and others of the transmissions are with relatively-inverted phase. At a receiver the received pilot signals 10 are extracted and combined so as to obtain an indication of the transmission channel characteristics. There are three improvements: (i) any continual pilots on the same carrier as inverted scattered pilots are also inverted in phase, (ii) those scattered pilots on alternate pilot-bearing carriers are phase inverted, even if this means that a given symbol has some inverted and some non-inverted, and (iii) at the receiver the non-inverted and inverted pilots are separated, interpolated in frequency and time, and then both added and subtracted.

Title: Improvements in or relating to electronic timepieces
Inventor: FUKUICHI TAKURO
IPC: G04G9/00
Filed: 1978-06-15
Granted: 1982-01-06
Abstract: A digital electronic timepiece having a multi-digit digital display for displaying the time count in a time counter which receives a divided down time signal from a time base signal generator. At least one settable time counter for storing a count corresponding to a desired time period is provided which is receptive of a time signal for decrementing the count thereof to zero. A plurality of display driving signals, each corresponding to one digit of display are generated wherein the display signals of successive digits are phase delayed with respect to each other and the frequency thereof is sufficiently low to produce visible flickering of display. Upon the sensing of the zero count in the timer counter, the display which is normally non-flickering, is driven with the display driving signals to produce a sequential flickering of the digits of the time display to provide a visual indication of the lapse of the desired time period.

Abstract: PCT No. PCT/GB95/00405 Sec. 371 Date Sep. 24, 1996 Sec. 102(e) Date Sep. 24, 1996 PCT Filed Feb. 27, 1995 PCT Pub. No. WO95/27273 PCT Pub. Date Oct. 12, 1995A remote telemetry metering system, includes one or more battery-powered metering units and a central data collection unit, each including a radio transceiver. The central data collection unit transmits a signal including power down time information and transmits instructions, which is received by each metering unit. Each metering unit extracts the power down time information and transmits instructions from the signal and, if appropriate, transmits data in response to the data transmit instructions; this data being collected by the central data collection unit. The metering units then interrupt the power supply to their transceivers for a period of time which is dependent upon the power down time information. The central data collection unit delays, for a slightly longer period of time before transmitting a further signal via its transceiver, at which time the power supply to the transceiver of each metering unit has already been resumed. By allowing the metering units to power down to a quiescent state under the control of the central data collection unit, flexibility is ensured and power consumption minimized.

Title: Process for heat-treating hydrates
Inventor: KROEHL PAUL
IPC: C04B11/036
Filed: 1992-03-19
Abstract: Both the drying and also the removal of the water crystalization take place carefully in a respective fluidized bed apparatus (A, B) without any danger of overheating. This is achieved by a complete homogenous fluidization through indirectly heated hot gas. A substantial quantity of energy is transferred via heat exchanger systems (4 or 12) in the fluidized layer. These are heated by heat carrying media. The constructional design of the fluidized bed apparatuses (A, B) which have a rectangular base outline ensures a narrow dwelltime spectrum and a pronounced temperature/moisture profile without the aid of differentially fluidized chambers. Because of the comparatively cold infeed zone and the careful heating which thereby arise the characteristics of the crystals are favourably influenced. The product is characterized by high quality homogenity. In the case of the calcining of moist gypsum no undesired gypsum modifications arise.

Granted: 1988-02-24
Abstract: An audio signal processor treats a digitally encoded signal. Units (3, 12) sample the encoded signal and units (8, 13) calculate from the sampled values a correlation function relevant to a particular time frame. The function value serves to control an adaptive echo cancellation algorithm. The sampled signal portions are truncated (2, 5) so that only the arithmetic sign bit of each signal portion contributes to the function calculation. An incoming signal sample is initially treated in an extraction block arranged to determine the arithmetic sign relevant to that signal, the resulting sign bits being fed in sequence to a shift register arranged to store a predetermined number of sign bits. Outputs are provided from selected locations in the register in accordance with a control logic select circuit.
