Patent EP-0568398-A2 (EP)
Inventor: MCDONALD NEIL ANDREW
IPC: G06K7/00

Abstract: A reader unit (10) for reading an inductively powered token, such as a tag, keyfob or credit card, has a reader coil (12) for producing a field to power the token. The amplitude Vcp of the reader coil waveform is sensed by a circuit (16, 17, 18) and regulates the voltage (Vcoil) applied to the reader coil (12) to ensure a constant voltage on the token irrespective of where it is placed in the reader coil field. Regulation is in accordance with the equation       vcoil = m(Vcp + c/m)           
 where c and m are constants. 
     A reference voltage Vref represents the constant value c/m. Resistors (30,31) sum Vcp and c/m which is passed through an operational amplifier (33) having a negative feed back loop with resistors (34,35) to give a gain of m. The working height of the token is extended whilst simultaneously widening the design tolerances of the token which is easier and cheaper to manufacture.

Abstract: A circuit for detecting harmonic lock of a phase-locked loop includes a frequency synthesizer (12) for receiving a reference clock signal and for generating an oscillator clock signal. A phase generator (26) receives the reference clock signal and generates a phase shifted version of the reference clock signal. A shift register (18) receives as an input the oscillator clock signal and is clocked by the phase shifted version of the reference clock signal to produce an output that is a repetitive sequence of logic states. A harmonic decode circuit (28) decodes the shift register output to determine which harmonic the phase-locked loop has locked onto. The shift register output signal may be used to force the phase-locked loop out of harmonic lock to a lower frequency of operation. In another embodiment, the phase generator (26) is coupled to the oscillator clock signal instead of the reference clock signal. The shift register (18) then receives the reference clock signal as input and a phase shifted version of the oscillator clock signal as the clock input.

Abstract: A charge pump assembly includes a storage capacitor having one terminal for a first supply potential and another terminal for pickup of an output potential. The assembly has one charge pump or two charge pumps being controlled by push-pull signals. Each charge pump includes a p-channel MOS transistor having a gate terminal being controlled by a first signal and having a drain-to-source path with one terminal being connected to the other terminal of the storage capacitor. A sliding capacitor has one terminal being connected to the other terminal of the drain-to-source path of the p-channel MOS transistor and another terminal being controlled by a second signal. An n-channel MOS transistor has a gate terminal being controlled by a third signal and a drain-to-source path being connected between a second supply potential and the one terminal of the sliding capacitor. A pulse shaper device is supplied by an oscillator device for generating the signals, in such a way that the p-channel MOS transistor is conducting only whenever the second signal is at a high level, and the n-channel MOS transistor is conducting only whenever the second signal is at a low level.

Abstract: An improved electrical connector for use in electronic assemblies to link electronic components in order to transmit electric signals or current. The connector (10) includes a wafer interface connective construction with at least one resiliently compressible contact (34) to provide a means across which electrical current can flow from one male pin (38) to another male pin (56) without placing the pins in direct contact with each other. The contact (34) retains its form and resiliency through its non-compressive retainment within the aperture of the wafer interface connective construction. Engagement and disengagement of the connector is facilitated, yet reliability and conductivity are enhanced. Further, the size and weight of the connector is reduced, and the assembly of the connector is facilitated. In addition, the pin contacts and the retainment components for the pin contacts are common to both halves of the connector which eliminates the need for socket contacts and their associated components.

Abstract: When a second synchronizing signal, an output from a synchronizing signal generating circuit, becomes synchronized to an input video signal, switching is made from a first synchronizing signal separated from the input video signal by a synchronizing signal separation circuit, to the second synchronizing signal by the switching action of a switch circuit based on a control operation performed by a timer circuit. When performing arithmetic operations between the current video signal and a delayed video signal in the direction of time axis, if variations in the synchronizing signal cycle occurs due to variations in the timing caused by jitter resulting from noise or waveform distortion, the time difference between the two video signals is maintained constant at all times, ensuring arithmetic operations in the correct time axis direction.

Abstract: A memory controller which makes maximum use of any processor pipelining and runs a large number of cycles concurrently. The memory controller can utilize different speed memory devices at their desired optimal speeds. The functions are performed by a plurality of simple, interdependent state machines, each responsible for one small portion of the overall operation. As each state machine reaches has completed its function, it notifies a related state machine that it can now proceed and proceeds to wait for its next start or proceed indication. The next state machine operates in a similar fashion. The state machines responsible for the earlier portions of a cycle have started their tasks on the next cycle before the state machines responsible for the later portions of the cycle have completed their tasks. The memory controller is logically organized as three main blocks, a front end block, a memory block and a host block, each being responsible for interactions with its related bus and components and interacting with the various other blocks for handshaking. The memory controller operates in system management mode to override any write protect status of memory so that the SMRAM can be located in the main memory space and be write protected during normal operations but be full usable during system management mode.

Abstract: An improved design for microwave bandpass cavity filters wherein dielectric resonator elements are mounted in dielectric blocks (there can be more than one resonator element per dielectric block). The dielectric blocks are in turn fitted within the filter housing, and the open ends are covered by shorting plates which are maintained in contact with each resonator surface. The shorting plates may be coated with a superconductive material. The structure results in significant size reduction over prior art filters. In addition, the new design is of higher structural integrity and helps to maintain a consistent output over a wide range of temperatures. By carefully choosing the dielectric materials to insure uniform thermal expansion of the component parts, the filter output is stable over a wide range of temperatures. This allows the filters to be tuned while at cryogenic temperatures, then returned to room temperature for storage or shipping, and finally return to cryogenic temperatures for operating purposes. The filters can be constructed with various configurations and can be operated in single mode, dual-mode, triple-mode, etc.
