Abstract: A transformerless oven timer which uses a 20 pin microcontroller connected to light emitting diodes. The microcontroller has 2 Kbytes of 8 bit read only memory and has software etched therein. The microcontroller can transfer power and voltage to the light emitting diodes when the oven is connected to, and powered by, an electrical outlet. The software etched into the microcontroller detects whether a resistor is connected to the microcontroller and converts a pin on the microcontroller from an input into an output. The software also synchronizes the microcontroller with the frequency of the electrical outlet to provide that the microcontroller keeps track of time. The transformerless oven timer also includes electrical circuitry connected to the microcontroller, where the electrical circuitry reduces the voltage and current provided to the microcontroller and to the light emitting diodes without using a transformer.

Abstract: Disclosed is an electronics device for use with a refrigerator/freezer for controlling the dispensing of ice cubes by an ice auger through a door flap when a cradle is pressed. The electronics device comprises a solenoid in operative connection with the door flap, and the solenoid is powerably connectable to a 120 Volt AC line power source. The electronics device also comprises a relay switch controlled by two NPN bipolar transistors in a Darlington configuration which are in parallel connection with a diode and a capacitor. The relay switch is also connected to the power source and connects the power source to the solenoid when the cradle is pressed causing the door flap to open. The power source powers the ice auger to dispense ice cubes through the door flap, and the capacitor causes the transistors to be biased on while the capacitor is charged to a voltage greater than a voltage of the diode.

Abstract: A speed detection signal sensor system for use with a vehicle. The system includes a signal sensing device positioned in a housing assembly. The housing assembly includes a reflective portion such as a mirror. The sensing device is positioned between the reflective portion and the housing. A sensor is positioned relative to the housing assembly and the reflective portion for sensing a speed detection signal which is directed towards the vehicle either from a forward position or a rearward position relative to the vehicle. A signal sensing indicator may be positioned relative to the housing assembly and generally in the reflective portion. Alternatively, the signal sensing indicator may be positioned externally of the housing assembly for attachment in a convenient location. The signal sensing indicator provides indicia that a speed detecting signal has been sensed by the detecting device.
