Abstract: An apparatus and method for supplying power to the peripheral circuits of a transmitter circuit, especially an HDMI transmitter circuit, is disclosed. In an HDMI transmitter the termination resistors of the output driver are part of the receiver. DC power for the driver is supplied through these termination resistors. In prior art implementations of circuits this power, supplied by the receiver circuit, is wasted in the DC set-up circuit of the differential line driver. In various embodiments, this wasted power may be recovered from the remote termination to power selected peripheral circuits of the transmitter. The use of this wasted power may reduce the total system power consumption.

Abstract: A composition that may be used to seal and strengthen the joints in an asphalt road surface and subsurface to prolong the useful life of the road is disclosed herein. The composition utilizes a polymer modified cationic maltene emulsion containing polymer modified maltene oils and resins, and surfactants/and wetting agents. The emulsion is applied to the longitudinal joints and other joints in the asphalt pavement surface. The emulsion reduces voids in the asphalt pavement and chemically improves the asphalt binder properties, thereby altering the modulus of elasticity of the asphalt binders so that the resistance of the pavement to tension is increased, and the water absorption of the pavement is reduced.

Abstract: Various embodiments of the invention include methods and systems for trimming electronic circuits using short laser pulses of near-infrared wavelength at a high repetition rate. The laser pulses ablate material from a spot on a circuit with minimal thermal and photoelectric disturbances to circuit performance. Minimal disturbance to circuit performance allows for repeated trimming and testing without pausing for circuit reinitialization. To optimize trimming, the laser pulses can also be adjusted responsive to the composition of the material ablated. In some embodiments, the system is configured to trim a plurality of circuits in parallel.

The reflectors are preferably located on a side of the light guide opposite to an output side of the light guide.

Abstract: An optical system with an LED light source utilizes a base with an inverted conical shape to conduct light to a phosphor layer. The phosphor layer emits light from both upper and lower surfaces. The base and a substantially mirror image cap element facilitate efficient extraction of the phosphor-generated light from the optical system so that the output of the system is omni-directional light suitable for common lighting applications. The system is very efficient in that nearly all the light generated by the LED is transmitted to the phosphor layer, and nearly all the light emitted from the phosphor layer is output from the system.
