Abstract: Signal quality in a region of a telecommunication system is improved by first determining a filtered transmitter power level that represents transmitter power levels in the region. Then the filtered transmitter power level is used to determine a new adaptive signal quality reference level. Finally, the new adaptive signal quality reference level is used to adjust the individual transmitter units in the region so that the actual signal quality experienced by the communication links in the region substantially equals the new adaptive signal quality reference level.

The driver is not required to confirm the state of charge of the battery with an indicator on a battery charger or within the passenger's compartment of the electric vehicle, but can easily confirm the state of charge of the battery from outside of the electric vehicle.

Abstract: An antenna alarm detection system includes first and second antennas, a transmission section, an antenna switch section, a reflected power detection section, and a comparing section. The transmission section transmits a control signal and speech communication information. The antenna switch section alternately switches and outputs the control signal transmitted from the transmission section to the first and second antennas in a predetermined cycle in a non-speech communication state in which only the control signal is transmitted. The reflected power detection section detects the reflected power of each of transmission signals from the first and second antennas. The comparing section compares the detected reflected power with a predetermined reference value, and outputs an alarm signal on the basis of the comparison result.

Abstract: A magnetic apparatus (10) is provided having a bottom plate (12), a top plate (14), a first magnet guide (16), a second magnet guide (18) and a magnet member (20) which is slidable upon a slide axis (22) through apertures (40) and (54) of first magnet guide (16) and second magnet guide (18) respectively. The magnetic apparatus (10) is shown in a closed position in FIG. 1 for use in conjunction with a reed switch (86) (see FIG. 3) mounted on bottom plate (12). In the closed position magnet member (20) is close enough to the reed switch (86) to magnetically toggle reed switch (86) and thus electrically toggle electrical circuit (100). When the magnetic apparatus (10) is moved in three-dimensional space so that reference plane (24) is changed with respect to gravity line (26) to a sufficient degree, then magnet member (20) will shift along slide axis (22) toward second magnet guide (18).

Abstract: A liquid level detecting system which utilizes audio frequency with components having sizes and values usually associated with RF frequencies, thereby providing the reliability and low cost of audio components with the small size typically associated with RF systems. A conductive element is mounted within a container, the conductive element is provided with an insulative coating.

In one application, the detector is utilized to sense the level of water in a fuel/water separator and, in a second application, a pair of liquid level detectors are utilized to control the operation of a bilge pump.

Abstract: A multi-purpose keyboard controller includes a matrix keyboard control circuit, a serial keyboard control circuit, a PC/AT port control circuit, and an external interface for RTC control. These control circuits are coupled in parallel with the interface logic of the computer system and use the built-in SMI interrupt mechanism of the computer system for reading and writing the keyboard or capturing keypress events. Software BIOS setup is employed to select one of the keyboard control circuits for utilization with the particular personal computer with which the system is employed. The interrupt scheme used by the keyboard interface uses SMI interrupts to the processor and SMI based software routines to read and write the values to and from the keyboard, thereby eliminating the need for dedicating a special hardware interrupt level; so that the system remains compatible with the DOS PC/AT Port 60/64h software interface.

Abstract: An electric alarm which includes a dual tone electronic chime, light emitting diode (LED) indicators, electronic circuitry, batteries, and with the exception of the AC adapter and the water sampler, all active and passive devices are housed in a small box to detect wet environments such as water that leaks from defective hot water heater tanks, flooded basements, storage spaces, room spaces below sea level, or any other spaces or tangible things not readily accessible or observable. It uses a water-activated-dielectric capacitor as a water sampler to absorb a small amount of water as the sample. And when it becomes wet or damp, the water dielectric signal controls the current required to energize the gate of the silicon control rectifier (SCR). In turn, the SCR turns "ON" a dual tone electronic chime and also turns "ON" a LED that simply glows. This action provides the audible and visual alert warning signals to indicate that the water does in fact exist.

Abstract: Automatic identification system for objects or persons by remote interrogation. The invention relates to an interrogating E/R (emitter/receiver) or gate associated with an answering E/R or tag having a digitized code identifying the same. The gate supplies four information types in the form of signals to the tags which answer "yes" or, by an absence of any answer, "no" until the gate has found their codes. When its code has been found, the tag is inhibited, thus permitting the detection of other codes. The invention more particularly applies to the monitoring of persons carrying answering E/Rs or to the billing of goods on sale in a large surface area.

Abstract: Method and apparatus for detecting mechanical vibrations and outputting a signal in response thereto. Art accelerometer package having integral display and control functions is suitable for mounting upon the machinery to be monitored. Display circuitry provides signals to a bar graph display which may be used to monitor machine conditions over a period of time. Control switches may be set which correspond to elements in the bar graph to provide an alert if vibration signals increase in amplitude over a selected trip point. The circuitry is shock mounted within the accelerometer housing. The method provides for outputting a broadband analog accelerometer signal, integrating this signal to produce a velocity signal, integrating and calibrating the velocity signal before application to a display driver, and selecting a trip point at which a digitally compatible output signal is generated.

Abstract: A glass break detector system (10) includes a low frequency (LF) detector (28) that is responsive to a pressure wave transducer (12) to detect the amplitude of a low frequency, generally sinusoidal acoustic wave signal resulting from a physical contact with a glass window. The LF detector includes a peak analyzer (42) that compares absolute values of sequential first and second amplitudes (P1, P2) of a low frequency signal derived from the low frequency acoustic wave signal to determine an appropriate alarm response. The LF detector enables the alarm if the absolute value of the first amplitude (P1) is greater than the absolute value of the second amplitude (P2) or if P1 or P2 amplitudes exceed saturation thresholds. The LF detector also includes a slope analyzer (40) that determines whether the low frequency signal exhibits atypical characteristics that generally indicate glass breakage.

Abstract: The device comprises a flat and elongated condenser with a piezoelectric dielectric material placed between two electrodes. This condenser is fastened to a barrier surface such as the glass pane of a display, a cupboard, or a glass window of a protected space. The condenser is connected with an electrometric amplifier, the signals of which are transmitted to an electronic alarm unit. When the glass pane is subjected to shocks or to mechanical stresses due to an attempted break-in, the condenser will generate electrical signals able to trigger an alarm when they exceed a certain threshold. The condenser and the amplifier may also be adjusted so as to trigger an alarm when the electrical field is modified by the movements of a dielectrical body within the protected region.
