Accessory interface node

A helmet accessory mounting system includes a mounting device configured to couple to an outer surface of a side of a helmet. The mounting device includes a plurality of mounting locations configured to removeably couple to at least one accessory. A plurality of the plurality of mounting locations each includes an electrical node. A power supply is coupled to the mounting device. An electrical supply line electrically couples the power supply to each of the electrical nodes and the electrical supply line is contained at least partially within the mounting device.

An improved fast settling bit slicing comparator circuit includes a comparator having a non-inverting and inverting input; the non-inverting input receiving an input signal; a filter circuit for receiving the input signal and being connected with the inverting input of the comparator; a positive feedback circuit interconnected between the output of the comparator and the non-inverting input of the comparator for introducing a predetermined hysteresis offset; the filter circuit including a filter resistance and filter capacitance having a reduced time constant sufficient to compensate for at least a portion of the hysteresis offset. Additionally, the positive feedback circuit may be interconnected with the inverting input of the comparator through the filter circuit for gradually reducing the effect of the hysteresis offset by reducing the differential voltage between the inverting and non-inverting inputs.

A method of operating a vehicle locating unit wherein an activation signal is received when the vehicle is stolen and in response to the activation signal, a signal indicating the vehicle has been stolen is transmitted. The receiver is energized for an actual duration Nperiodically to listen for the activation and other signals. Estimating how long the receiver has been on includes incrementing a counter at a count resolution where Nis typically at least sometimes less than the count resolution. Estimating the total amount of time the receiver was energized is based on a measured on time after it converges with the actual on time.
