Filed:

Oct 21, 2009

Appl. No.:

12/589288

Inventors:

Stephen Bourque - Littleton MA, US

Assignee:

LoJack Operating Company, LP - Canton MA

International Classification:

H04B 17/00
H04B 1/40

US Classification:

455574, 455 6711

Abstract:

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.

US Classification:

327 90, 327 77, 327205

Abstract:

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.

International Classification:

B01D 3530

US Classification:

55471, 55486, 55505, 55508

Abstract:

An air purifying device is provided for removing airborne particles. The device includes a housing including an air inlet and an air outlet. A fan is positioned within the housing for drawing air into the housing through the air inlet and expelling air through the air outlet. A filter assembly is positioned within the housing between the air inlet and the fan. The filter assembly includes a frame and a filter element mounted to the frame. The device also includes a hanger and an elongate hanger support that removably extends within the hanger. Either the hanger or the elongate hanger support is coupled to the frame while the other is coupled to the housing. The hanger can include a channel or a pair of opposed legs configured to form a gap.

Abstract:

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.
