Patent GB-2349544-A (GB)
Title: Covert communication system
Inventor: WILKINSON ROBERT G
IPC: H04L27/26
Filed: 1990-04-02
Abstract: Data is transmitted covertly using <WC 1>a large number (4096) of narro<WC 1>wband channels spaced over a 1MHz bandwidth <WC 1>at a signal level below that of background noise. Input data to be transmitted is demultiplexed so that sections of data are transmitted in groups of channels at 25 baud,DPSK modulated using difference phase shift key (DPSK) and added for transmission as an analog signal. The inventor envisages that 16DPSK can be used because of the coherent and semi-coherent channel addition signal processing which can be achieved. In the receiver the signal is converted to digital form then processed by an FFT circuit to produce 4096 frequency bins. Differential phase detection is carried out and running averages used in each channel to determine the proportion of times that the phase difference falls within allowed limits. A discrimination level determines whether individual channels should be excised because of noise corruption. The remaining channels in groups are then added together to determine each data phase/received. The <WC 1>measured phase vectors are added vectotially using semi-coherent addition and the vector sum is used to determine the data bit. In a second arrangement the channels of any one group are arranged in bunches of about 10 spread over a bandwidth of 10 kHz (the experimentally determined coherence bandwidth) with the bunches spread over the 1MHz bandwidth. The bunch channels are added coherently and the resultants are added semi-coherently as before to determine the group data. The group data is then multiplexed to reproduce the high data rate input data. The arrangement allows very high data rates to be transmitted with each of the 4096 channels carrying only 25 baud.

Title: Handling division by zero.
Inventor: DANDEKER KASHINATH NARAYAN
IPC: G06F7/52
Filed: 1991-10-23
Abstract: The invention is a device which stores numbers and their signs and enables zero divided by zero to yield the result zero by a process of virtual division. In the description, the process of division is explained in terms of repeated subtractions of the divisor from the dividend to compute the quotient and the remainder according to a pro-determined procedure based on the sign of the remainder obtained during the process of division. The device differentiates between the operation zero divided by zero which yields a zero result and the operation any number other than zero divided by zero which does not yield a finite result. If the numerator is zero, a stored zero is output by the device. If the denominator is zero but the numerator is not, then a stored specified error indicator is transferred to a quotient register. If neither numerator nor denominator is zero, a further device or circuit is activated to compute the quotient and pass it to the quotient register. The device may be electronic, electrical, electro-mechanical or pneumatic, or implemented as logic circuits or in software.

Title: Medicament dispensing device
Inventor: HOLROYD MICHAEL JOHN
IPC: A61M15/00
Filed: 1992-05-29
Abstract: An inhaler for use with a drug delivery system (25), e.g. an aerosol dispensing container, has a diaphragm 440 and an inverted cup-shaped member 420 defining therebetween a low pressure air chamber 600 for applying a resisting pneumatic force capable of preventing actuation of the aerosol container by a loading spring 460. The resisting low pressure is released by a breath-actuator vane 550 comprising a flexible diaphragm 600 for sealing a valve port 495, the opening of which releases said positive or negative pressure. The flexible diaphragm is carried by the vane 550 such that, on initial movement of the vane, the diaphragm flexes as it is held by said positive or negative pressure against the valve seat until it is finally removed therefrom on further movement of the vane. With the dust cap 510 closed, the spring 460 is held closed and the pressure chamber volume is a minimum. On opening of the cap, the spring urges the inverted cap downwardly which increases the pressure chamber volume until the underpressure developed therein balances the action of the spring. On inhalation, vane 550 is pivoted to open the valve port 495 whereupon spring urges the inverted cup and the aerosol further down to dispense the drug. <IMAGE>
