Title: Aircraft seat
Inventor: BETTELL RAY
IPC: B64D11/00
Filed: 2005-11-15
Abstract: An aircraft seat (1) is installed in a cubicle (2) able to provide privacy via a hidden, sliding/pocket door drawn to a seat-side end (3) of a divider (4) between adjacent seats from within a facing panel (5) of the next divider (6) in the line of seats. The divider (4) provides a recessed backing (7) for the seat (1); whilst a return recess (8) provides foot rest space (9) opposite the seat. The dividers are generally S-shaped. The seat (1) may be a double seat, in that it comprises a convertible seat (11) and a fixed seat (12) immediately next to each other. The fixed seat provides an alternative seating position when the convertible seat is in bed configuration and a seat for a friend when the convertible seat is in seat configuration. Not only the convertible seat, but also the fixed seat have seat belts, the latter seat's belts being provided in case of turbulence during use. The convertible seat has a seat squab (14), a backrest (15) and a leg rest (16) both pivotally connected to the seat squab. These are reclinable via a conventional mechanism. For conversion of the seat to a bed a bed portion (31) is withdrawn from a stowed position, which may extend between the cabin deck (32) and a shelf (28) alongside the space (30) between the seat squab (14) and the foot rest (24), and set up over the space (30). When not in use, the bed portion is stowed upright beneath a lid (33) in the shelf, with its lower/outer end located by pins (not shown) in tracks (34). For use, the lid may be opened and the bed portion is then drawn up until the pins reach the top of the tracks (34). It is then swung over the space (30). A leg (35) is then pivoted to the under-side of the bed portion and springs out to a strutted (36) position, in which its distal end engages with a load bearing point (37) provided in the floor of the cubicle for support of the distal end of the bed portion. The proximal end of the bed portion pivots into a position such that it is supported on a panel (38) beneath the shelf. The bed portion has a rigid base (39), which faces the space (30) when stowed and an upholstered top (40). This is level in bed configuration with the foot rest (24).

Title: Surgical implement detector
Inventor: FABIAN CARL E
IPC: G08B1/08
Filed: 2006-02-08
Abstract: Provided is a detector system for detecting a plurality of items each having at least one RFID tag attached thereto. The detector system may include a presence detector and/or a message detector. The presence detector may include a signal reader which receives modulated carrier frequencies from the RFID tags during a predetermined response time period for comparison to a reference level. The signal reader may be configured as a power integrator or a constellation discriminator. The power integrator sums the power contained in signals transmitted by the RFID tags by integration for comparison to an environmental noise level measurement taken during a quiet period. For the constellation discriminator, bits contained in the modulating message are compared to the bit pattern of a predetermined reference constellation. The detector system may be configured as a 3-state detector which combines the presence detector with a message detector that indicates the identification code of the RFID tags.

Title: Dispense tap with two valves operated by one actuator
Inventor: CARTER DAVID PETER
IPC: B67D1/00
Filed: 2008-01-11
Abstract: A beverage dispensing tap 1 has an inlet 9 for a first beverage component, such as a diluent, and an inlet 11 for a second beverage component, such as a concentrate, and an outlet 7 for a mixture of the first and second beverage components. The inlet 11 for the second beverage component is downstream of the inlet 9 for the first beverage component and each inlet 9,11 has an associated valve 13, 17 operable by a common actuator (not shown). The valve associated with the second inlet 11 has a valve member 17 arranged so that the second beverage component is added to a stream of the first beverage component passing through the valve member 17. When the first component is a diluent such as carbonated water, it is retained under a back pressure which reduces breakout. It also forms a barrier between the walls of the nozzle and any syrup dispensed as a second component, thus creating a more hygienic environment. The tap has the appearance of a dispense tap for alcoholic beverages.
Patent GB-2445112-A (GB)
Title: High speed acknowledge protocol for OFDM UWB systems
Inventor: STOYE WILLIAM
IPC: H04B1/69
Filed: 2006-12-22
Abstract: An Orthogonal Frequency Division Multiplex (OFDM) system communicating via Ultra Wideband (UWB) packets in burst mode achieves a payload rate of 480 Mbps by employing a protocol whereby acknowledgement data 402 relating to a previous-but-one data packet replaces OFDM synchronization data in a Minimum Interframe Spacing Gap (MIFS) 36. There is then a final acknowledgement 404 of all packets in the burst. UWB receivers can retrieve acknowledgement data by detecting phase shifts directly, with no need to perform a Fast Fourier Transform (FFT) on the synchronization data. False acknowledgements from third parties sending synchronization symbols is avoided by using only sequences which would be illegal or invalid if used in synchronization, eg. by omitting the short burst sequences entirely. The interval between the acknowledgement and the start of the data packet is less than one OFDM symbol in duration, which is possible in UWB networks within a range of around 100m.

Title: Method for creating tables in electronic forms
Inventor: RINGLER MARCEL
IPC: G06F17/24
Filed: 2007-03-09
Abstract: A form table system and method are disclosed, for creating fillable form tables that are part of electronic documents. The form tables may include an unlimited number of cell array vectors, e.g., rows or columns, confined to a limited space in the electronic document. The form table system enables a user to quickly and easily generate a form by placing a table object on a form page, populating the table object with other desired objects, and defining \characteristics, such as row height and number of visible rows for the form table. As the form is filled in with data, where the number of entered rows exceeds the number of visible rows, the form table extends such that the document is printed in its original form, but the additional information is still available both for viewing and for printing.

Title: Electric circuit for turbine flow meters
IPC: G01F1/115
Filed: 1975-03-11
Abstract: 1492632 Electric flowmeters COMPTEURS SCHLUMBERGER 11 March 1975 10010/75 Heading G1N The voltage signals from a turbine type flowmeter are fed through an amplitude or frequency cut-off unit whose threshold value is adjusted to provide automatic compensation between the pulses lost on starting and gained on stopping, due to the inertia of the moving members. The turbine speed W o  at which this compensation occurs is established experimentally and defines the frequency threshold, and an additional frequency comparator circuit enables the first pulse to be fed out by sensing a long interval after receipt of the last pulse. In an embodiment sensing the amplitude of the turbine signals, the cut-off voltage is determined from the speed W o  as modified by the integral of each successive positive half-cycle. As shown, Fig. 3, the positive half-cycle of the flowmeter signals E are directed by rectifier 8 to an integrator 10 and to a comparator 11. The negative half-cycles are directed by rectifier 9 to monostable 14 which closes switch 12 at the start of the negative half-cycle, to feed the integrated voltage to terminal E 2  of comparator 11, and closes switch 16 at the end of the negative halfcycle to bring the integrated voltage back to zero. If the sensed positive half-cycle voltage at e 1  is greater than the integrated voltage at e2, suitably modified by a factor of W o , a metering pulse is fed out of comparator 11 at S.
