Abstract: A heater, humidifier or fan has a control circuit including a microcontroller having an algorithm for controlling power to the appliance. The power to the appliance is varied in accordance with a target temperature/humidity signal and an actual temperature/humidity signal. Preferably, a sensor electrically connected to a clock oscillator input of the microcontroller is used to vary the clock oscillator frequency in response to changes in ambient temperature/humidity. The frequency of the clock oscillator varies in response to changes in temperature/humidity and the microcontroller in response to the frequency of the clock oscillator variably controls the power to the appliance.

Abstract: Sinusoidal timing reference signals, each of which is associated with a different suppresed-sync scrambled-priority television channel signal, frequency modulate associated carrier frequency signals for producing modulated carrier signals that are combined with a continuous wave (CW) sinusoidal carrier frequency signal. After low-pass filtering to block harmonic frequencies that may interfere with the video carriers of composite television signals, only the fundamentals of the CW and modulated carrier signals are combined with non-scrambled and/or scrambled composite television signals for transmission to subscriber's equipment. In a descrambler at a subscriber location, the CW carrier signal is mixed with the modulated carrier signals to produce frequency modulated IF signals containing timing information for associated priority television channel signals. Upon request of a subscriber, a particular IF signal is demodulated to reproduce a timing reference signal here that is operated on to produce timing pulses that are slightly wider than the pulse width of, and delayed in time with respect to, suppressed horizontal blanking pulses carrying synchronization pulses in the associated scrambled composite television signal. The timing pulses drive a switched attenuator or amplifier for restoring the level of suppressed horizontal synchronization and blanking pulses in the associated scrambled composite television signal, and thereby descramble it.

Abstract: A tactile matrix switch has a planar electrically conductive layer dielectrically spaced between contacts of individual switch elements and an actuating mechanism such as a finger on the body of a human being who may carry an electrostatic charge. Some switch contacts are electrically connected through external circuitry to ground. The conductive layer is also electrically connected to ground. When a human operator carrying an electrostatic charge brings his finger near the face of the matrix switch for applying a tactile force to actuate an individual switch element, the conductive layer electrically conducts the electrostatic charge to ground and away from the switch contacts for protecting the electrical circuitry connected to the latter. In one embodiment, the conductive layer is electrically conductive printer's ink, having a resistivity of less than 50 k ohms per square, that is silk screened onto the back of a face plate of the matrix switch. In an alternate embodiment, the conductive layer is printed onto the same broad side of a flexible dielectric plate to which the tactile force is applied, switch contacts being formed on the opposite broad side thereof.
