Title: Linear amplifier with automatic adjustment of feed forward loop gain and phase
Inventor: LIEU WINSTON H
IPC: H03F1/32
Filed: 1990-10-17
Granted: 1995-06-20
Abstract: A linear amplifier includes a feed forward circuit which is operative to eliminate distortion of the amplified signal by utilizing a second circuit path parallel to the amplification path to generate a distortion cancellation signal and combine it with the output of the amplification path to cancel the distortion. The gain and phase of the feed forward circuit is automatically adjusted by discrete steps through the operation of a stored program controller. The initial adjustment step is set at some minimum discrete value and its effect on the cancellation level of the feed forward circuit is evaluated. If the cancellation level does not change by a specified amount the adjustment step is increased by a discrete amount. Adjustment of the cancellation level is continued by discrete steps under control of the stored program control until a desired cancellation level is achieved. The number of step adjustments permitted is preset at some value. If the allotted number of step adjustments fails to achieve the desired response, the stored program control checks for the existence of possible fault conditions in the feed forward circuit.

Title: Golf ball retriever
Inventor: TSUKAMOTO JACK K
IPC: A63B53/14
Filed: 1991-04-02
Granted: 1995-02-21
Abstract: A golf ball retriever includes a self-contained module having a plurality of curved, resilient prongs in the form of cantilevered springs and a housing with a side wall, an open end and a closed end. An end cap having an aperture associated with each prong is disposed across the open end of the housing and retains the prongs. One of the prongs has a shoulder cooperating with a portion of the end cap to form a latching mechanism. A push button arrangement disengages the latching mechanism allowing an axial compression spring to move the prongs from a first position having the prongs substantially dis-posed within the housing to a second position having the prongs sub-stantially extending from and through the housing's open end. The resilient, elastic prongs bias the push button arrangement toward a latched position. The cantilevered configuration of the prongs places them in a biased relationship with the side wall of the housing and urges the prongs toward the second, extended position. The coopera-tion between the bias of prongs and the bias of the axial spring per-mits actuation of the golf ball retriever using an axial spring having a smaller spring rate and a shorter length than required to fully extend the prongs if the spring rate of the prongs were not present.

Title: Video display apparatus with kinescope spot burn protection circuit
Inventor: GURLEY THOMAS DAVID
IPC: H04N9/64
Filed: 1991-04-04
Granted: 2000-10-17
Abstract: A television receiver includes a kinescope spot burn protection circuit comprising a capacitor coupled between a source of blanking signal and a control grid of the kinescope for applying negative grid cut-off bias to the kinescope in response to the blanking signal. The amplifier is of the cascode type having a minimum output voltage for peak white levels of a video signal applied to the cathode. The protection circuit includes a potential divider for biasing the kinescope at a positive voltage level related to the minimum output voltage of the amplifier during normal operation of the receiver to maximize the brightness of displayed images.      The protection circuit also includes a breakdown device in the potential divider for limiting the maximum grid bias voltage to a level less than the minimum output level of the amplifier but greater than the positive voltage level provided by the potential divider to thereby avoid forward biasing the grid of the kinescope upon termination of the blanking signal which otherwise could occur during recharging of the capacitor.

Granted: 1995-03-28
Abstract: In a communications network having time-dispersed signals, there is provided a mechanism for soft decision decoding. It comprises: radio reception of a time-dispersed signal, at least partly equalizing those time-dispersal effects, recovering informa-tion contained in the signal, multiplying with that recovered information the absolute value of that at-least-partly-equalized signal (scaled by a number derived from channel conditions over a time during which at least part of the information to be recovered is distributed), and error-correcting the multiplied information by a Viterbi algorithm channel decoding scheme of error correction. Accordingly, soft decision information is generated from whithin the equalization process itself.
