Latch control methods and systems are disclosed, including a latch that receives power from a motor associated with a latch. A sensor can be provided for monitoring the current consumption of the motor. A microcontroller can control the latch and/or the motor, based on the current consumption data received from the sensor concerning the current consumption of the motor. Monitoring of the current waveform of the motor therefore provides speed and direction feedback data for control of the latch. Additionally, a microprocessor can process instructions for controlling the interaction of the motor, the latch, the sensor and/or the microcontroller. Such a current monitoring control system is made possible by variation in current consumption of the motor during rotation as a result of commutation, which can be interrogated by measuring the voltage drop across the motor or a shunt resistor, or through the use of other current sensors, such as, for example, a Hall-effect type current sensor.

Angular position sensing apparatuses and methods are disclosed. An angular position sensing apparatus can include a rotatable base and two or more magnets located proximate to one another upon the rotatable base. The magnets are generally magnetized parallel and opposite to one another to create a uniform magnetic field thereof. Additionally, a sensor can be located external to the two magnets, such that the sensor comes into contact with the uniform magnetic field to sense a change in angular position associated with the rotatable base.

A connector block for connecting a plurality of electrical connectors includes a molded housing having a face. A plurality of female connectors are integrally molded within the face of the housing, each female connector having a well molded into the face of the housing and a receptacle extending from a bottom of the well. A threaded cylindrical bushing is integrally formed within the well around each receptacle. At least one male connector is also integrally molded within the housing.

A sensing and control circuit for power line shorts works especially well for sensor or actuator devices controlled through a microcontroller. A power control circuit is placed between a pin of a programmable microcontroller and a sensor or actuator device to act as a short detector and switch to control power to the device. A capacitor in the power control circuit is charged and sensed by a single pin of the microcontroller to regulate a transistor which switches power to the device.
