A clocking system disclosed herein includes a delay locked loop (DLL) circuit with a plurality of delay elements, where the DLL circuit is configured to receive a clock input signal and generate a plurality of clock output signals. The clocking system also includes a feed-forward system configured to increase the speed of the clock signal transmission through the delay elements and to enforce symmetric zero crossings of the clock signal at each of the plurality of delay elements.

Scaleable DLL clocking system

A voltage mode laser diode driver selectively turns on and off a laser diode. An output stage has an output node configured to be connected to one of the terminals of the laser diode. Depending upon implementation, an active swing controller drives the output stage in a manner that substantially prevents inductive kickback from causing the output node voltage to swinging above the voltage level at the voltage output of the power supply, or swing below ground. The output stage provides a discharge path around the laser diode to shunt current associated with the inductive kickback, and substantially eliminates ringing on the output node of the output stage while the laser diode is off. A power supply controller adjusts the voltage level of the voltage output of the power supply so that current through the laser diode when on and emitting light is substantially equal to a predetermined desired current.

Power efficient laser diode driver circuit and method

A method and system to enhance accuracy of measurement of distance Z in a TOF system dynamically provides tight control over the phase and/or timing relationship of clock pulses used in the TOF system. Enhanced frequency control is imposed over a high speed oscillator whose output(s) control a timing generator, whose outputs are coupled to circuitry associated with the detection array in the TOF system, and with the TOF clock timing circuitry. The timing generator is coupled to a delay locked loop (DLL) and/or phase lock loop (PLL), which loop(s) are feedback coupled to the waveform circuit that drives the source of electromagnetic energy emitted by the TOF system.

Method and system to enhance timing accuracy for time-of-flight systems

A surveillance apparatus and method for the surveillance of traffic are provided, in which the apparatus includes a housing for substantially completely enclosing and concealing a law enforcement vehicle therein, and a one-way window extending around part or nearly all of the housing, such that a vehicle operator in a vehicle inside the housing may visually monitor traffic, while the window prevents the vehicles in traffic from visually determining whether a vehicle is or is not present in the apparatus.

Surveillance apparatus

A wind line power system in which a series of rigid rods are connected end-to-end to permit relative angular movement and transmission of axial torque from one rod to the next, with propellers extending laterally from and coaxial with each rod to convert wind force vectors substantially parallel to the rods to cumulative unidirectional axial torque on all of the rods which in turn drives an electrical generator.
