Abstract: Abstract of the Disclosure A shock absorber mount is described as having two pressed fittings which are mounted in end-to-end relationship.  Each insert has two rigid, radially spaced cylindrical sleeves which are separated by a resilient rub-ber insert.  The inner sleeve of the vertically lowermost fitting, when the fittings are properly mounted on, for example, an automobile frame, extends upwardly beyond the associated outer sleeve and is coated with rubber to enter a hollow bore formed by the inner sleeve of the upper fitting.  The extension allows the lower fitting to initially absorb an upwardly applied axial force until it moves into shock absorbing relation with the upper fitting.  The extension also acts to bolster the radial shock absorbing characteristics of the upper fitting to provide improved shock absorbing characteristics of the mount; namely, low axial shock absorption and high radial shock absorption.

Title: Analog to digital conversion with noise reduction
Inventor: PARKS ROBERT A
IPC: H03M1/08
Filed: 1990-12-14
Granted: 1999-06-01
Abstract: An analog-to digital converter (10) employs a capacitor circuit (12) for integrating a sample of an input signal (20) during a predetermined interval of time and, thereafter, the capacitor (42) is discharged at a predetermined rate until the intergration voltage is equal to that of a reference. The discharge time serves as a measure of the amplitude of the input signal. A measurement interval is established which is equal to an integral number of cycles of each of the possible values of frequency of the A.C. excitation. The signal integration interval has a duration less than or approximately equal to the shortest period of the A.C. exitation, this being the period of the highest frequency A.C. excitation. The signal  integration is repeated periodically at each third half-cycle of the highest frequency excitation so that the total integration time experienced during positive half cycles is equal to that experienced during negative half cycles of any of the plurality of excitation frequencies. This cancels the effect of noise due to signal polarity.

Title: Self-adjusting recovery algorithm for a microprocessor-controlled setback thermostat
Inventor: ADAMS JOHN T
IPC: G05D23/19
Filed: 1992-09-24
Granted: 2000-08-08
Abstract: A recovery algorithm for a setback thermostat uses the intersection of the space temperature with a sloped recovery temperature line which approximates the change in temperature as a function of time during recovery of the temperature controlled space from a setback temperature, to determine the time at which recovery to the occupancy temperature should begin. The thermostat starts recovery when the current space temperature crosses the recovery temperature line. A useful feature of the apparatus and method which implement the invention, computes and constantly updates the slope of the recovery temperature line. The update of the recovery temperature line slope is based on miss time, i.e., the time between actually achieving the desired next set point temperature and the next set point time associated with the next set point temperature. If the heating or cooling load on the space changes, the recovery temperature will frequently cross the recovery temperature line at a different time, causing recovery to start at a time more compatible with the current heating or cooling load in order to complete recovery at or near the desired time.

Title: Circuit to detect the hook status and ringing at the cpe end of a telephone network
Inventor: HORIUCHI EDWARD M
IPC: H04M3/02
Filed: 1992-11-06
Granted: 2001-01-30
Abstract: A circuit for indicating the status of a telephone line at the CPE end, where the status is either on-hook ringing, or off-hook is disclosed. The telephone line is the normal two-wire telephone line. First, a transconductance amplifier converts a floating voltage difference between the two-wire telephone line into a current. The current is proportional to the voltage difference. Next, a current to voltage converter converts the current from the transconductance amplifier to a single ended ground referenced voltage. The single ended voltage is proportional to the current from the transconductance amplifier, thus the single ended voltage is proportional to the voltage difference across the two-wire telephone line. A voltage controlled switch is turned ON when the single ended voltage is greater than a predefined value indicating the on-hook status. When the single ended voltage is below the predefined value, the voltage switch is turned OFF indicating the off-hook status. Finally, the ringing status is detected when the voltage controlled switch is turned ON and OFF with a repetitive cycle proportional to the frequency of the ringing.

Abstract: Synthesizer radiating systems providing efficient wideband operation incorporate a radiating element (20a), such as a loop, dipole or whip, which has dimensions which are small relative to wavelength in the radiated frequency band. Energy dissipation is substantially reduced by cycling stored energy back and forth between a radiating element (20a) having a first reactance and a storage element (22a) having the same or opposite reactance, in order to achieve energy efficiency along the lines of a narrowband tuned-circuit antenna. wideband operation is achieved by synthesizing a representation of an input waveform (at 28) by actively controlling (30) solid-state switching devices (24), responsive to rate control and direction control parameters, which are interactive with the energy transferred between the opposite reactances. Higher efficiencies are achieved by bipolar circuits providing separate positive and negative energy transfer paths between a radiating element and a storage element. Systems as described provide relatively high radiated power levels with broadband operation and reduced power supply requirements, permitting provision of readily transportable units with small antennas for applications in which combinations of size, radiated power, bandwidth, power use and mobility are important.
