Title: Programmable integrated circuit capacitors
Inventor: AUSTIN KENNETH
IPC: G11C27/00
Filed: 1991-03-27
Abstract: Programmable (IC) capacitors are implemented using a capacitive multiplier technique. Programmable capacitors comprise essentially three elements, a capacitor (C1) and one or two capacitor multipliers (M1 and M2). Capacitor (C1) is connected to the input of a first buffer circuit (B1) while programmable resistors (RP1 and RP2) are connected in series between the input and output of the buffer (B1), an output being taken from the junction between the first and second programmable resistors. By this arrangement of components, the ratio of the set values of the two programmable resistors (RP2 and RP1) determines the amount by which the capacitor (C1) value is multiplied. The effective capacitance with two multipliers (M1, M2) approximates to (RP2/RP1) x (RP4/RP3) xC1. The value of programmable resistor RP1 is adjusted in accordance with an analogue signal (CCV) produced by a compensating circuit (Fig 2) to compensate for the manufacturing/processing variations of capacitor C1. <IMAGE>

Title: Vcr control of cable converter unit (cable box)
Inventor: KIM SUNG JO
IPC: H04N5/00
Filed: 1992-12-10
Abstract: A VCR includes circuitry for detecting the presence of a television signal and control code transmission circuitry for remotely controlling a cable box. Because the VCR is coupled to the output of the cable box, the VCR can monitor the television signals received from it to ensure that commands from the VCR are executed. A skip list programmed into a VCR may be used to control the cable box. That is, in response to a channel up command received by the VCR, the VCR would not change channels itself, but rather controls the cable box to select the next preferred channel entered in the skip list of the VCR. In this mode of operation, the channel tuning keys (e.g., CHAN UP, CHAN DN) of the VCR remote control 125 are used to control an external source of signals, while the VCR mechanism control keys (e.g. PLAY, STOP, RECORD, FAST FORWARD) control the operation of the VCR. <IMAGE>

Patent GB-945531-A (GB)
IPC: G03B7/085
Abstract: 945,531. Photo-electric cinematograph camera exposure and frame speed control. BELL & HOWELL CO. Nov. 24, 1961 [ Dec. 19, 1960], No. 42073/61. Headings G2A and G2E. [Also in Divisions G1 and H2] A cinematograph camera comprises a photoelectric exposure control including a magneto responsive to frame speed to vary the control. Provision is made for adjusting the camera speed setting member from a "stop" position in which the drive is locked to "run" (normal speed operation), "single shot", or "slow motion" operation. The camera speed governor comprises a saucer shaped member 50 and a castellated member 49 of non-magnetic material, e.g. polystyrene between which are located magnetic balls 27. As the motor speed increases, balls 27 move outwards, pushing member 50 against a brake 64 which is positioned longitudinally to set a desired speed. The magneto comprises magnetic core surrounded by a coil 24 located alongside the path of rotation of balls 27. The A.C. current induced in the coil varies in accordance with the radius of this path and consequently with the camera speed and is used in opposition to the photo-cell to vary the exposure meter current and hence the camera diaphragm setting (see Division G1). In a modification Figs. 10 and 11, (not shown) the castellated member is magnetic and its longitudinal movement affects the magneto.
