Patent GB-2081458-A (GB)
Title: Voltage comparitors
IPC: H03K3/0233
Filed: 1979-03-06
Abstract: A voltage comparitor or level detector comprises a differential amplifier the input terminals of which are formed by the gates of two IGFET's Q1, Q2 which have different threshold voltages due to the use of differently doped semiconductor material for their gate electrodes. This structure provides a stable input offset for the amplifier which is used as a reference. The input voltage and a reference level are applied to the input terminals and the output of the amplifier is determined by the difference between the input p.d. and the input offset. The values of the source currents I1, I2 may be adjusted to provide temperature compensation. In an alternative arrangement the input transistors Q1, Q2 are arranged in a common source configuration with constant current drain supplies. The arrangement may be used as a battery voltage level detector by applying the battery voltage (via a potential divider) to one input and a fixed level (e.g. VDD or VSS) to the other input. Circuits incorporating such arrangements for providing low battery indication e.g. for an electronic timepiece are described. <IMAGE>

Patent GB-2112981-A (GB)
Title: Interrogating system for remotely monitoring tire air pressure
Inventor: VENEMA HARRY JAMES
IPC: B60C23/04
Filed: 1982-01-05
Abstract: The air pressure in a tire is monitored by transmitting an electromagnetic interrogating signal (specifically a radio frequency signal) from the vehicle to a passive transponder, affixed to the wheel on which the tire is mounted, in communication with the air pressure within the tire. When the pressure is normal, a semiconductor diode (24) and an antenna (24a) in the transponder will be shielded (21) from radiation and therefore no response will be made to the received interrogating signal. On the other hand, abnormal air pressure in the tire causes the antenna to become unshielded and exposed to the interrogating signal radiated from the transmitter (31-36), whereupon the diode reacts to the received signal and develops therefrom a response signal which is retransmitted from the antenna and includes, among other signal components, the second harmonic of the interrogating signal. A receiver (31,37-42), tuned to the second harmonic, produces from the response signal an indication (preferably on the vehicle's dashboard) that the sensed tire air pressure is abnormal. <IMAGE>

Title: Record verify and optimize system
Inventor: COLEMAN CHARLES H
IPC: G11B5/008
Filed: 1983-04-14
Abstract: A method and apparatus are disclosed for enabling the continuous monitoring of recording circuit performance and the automatic optimization of the recording process in a rotary head recorder having a plurality of recording heads. A calibration signal is recorded by each recording head onto the overlap area of a moving magnetic tape medium. A fixed monitor head subsequently detects components of the recorded signal, the magnitudes of which are squared and retained in sample and hold units. The sampled and held values are periodically used to construct an outputted value commensurate with recording circuit performance. Optimization is accomplished by varying the recording drive level of a recording head about a predetermined point during a series of successive overlap periods. A DC error voltage is derived from the respective outputs resulting from such variation, and used to shift the recording drive level of that head towards a point of optimum playback output. <IMAGE>
