Regulation of Wavelength Shift and Perceived Color of Solid State Lighting with Intensity Variation

Exemplary embodiments of the invention provide a system, apparatus, and method of controlling an intensity and spectrum of light emitted from a solid state lighting system. The solid state lighting has a first emitted spectrum at full intensity and at a selected temperature, with a first electrical biasing for the solid state lighting producing a first wavelength shift, and a second electrical biasing for the solid state lighting producing a second, opposing wavelength shift. Exemplary embodiments provide for receiving information designating a selected intensity level or a selected temperature; and providing a combined first electrical biasing and second electrical biasing to the solid state lighting to generate emitted light having the selected intensity level and having a second emitted spectrum within a predetermined variance of the first emitted spectrum over a predetermined range of temperatures.

Reversible resistive memory using polysilicon diodes as program selectors

Embodiments of reversible resistive memory cells using polysilicon diodes are disclosed. The programmable resistive devices can be fabricated using standard CMOS logic processes to reduce cell size and cost. In one embodiment, polysilicon diodes can be used as program selectors for reversible resistive memory cells that can be programmed based on magnitude, duration, voltage-limit, or current-limit of a supply voltage or current. These cells are PCRAM, RRAM, CBRAM, or other memory cells that have a reversible resistive element coupled to a polysilicon diode. The polysilicon diode can be constructed by P+ / N+ implants on a polysilicon substrate as a program selector. The memory cells can be used to construct a two-dimensional memory array with the N-terminals of the diodes in a row connected as a wordline and the reversible resistive elements in a column connected as a bitline. By applying a voltage or a current to a selected bitline and to a selected wordline to turn on the diode, a selected cell can be programmed into different states reversibly based on magnitude, duration, voltage-limit, or current-limit. The data in the reversible resistive memory can also be read by turning on a selected wordline to couple a selected bitline to a sense amplifier. The wordlines may have high-resistivity local wordlines coupled to low-resistivity global wordlines through conductive contact(s) or via(s).

Fuel cell system power control method and system

A fuel cell is placed in parallel with a battery via a mechanical switch. The voltage is held nearly constant by the battery and the power flow is controlled by adjusting the fuel cell operating parameters (such as temperature or air flow) and by opening and closing the mechanical switch. The result is a system that operates at nearly constant voltage without the need for an expensive power conditioning system. The output of the system can then be processed via a traditional power conditioning system such as an inverter or dc-to-dc converter without the need for a wide range of input operating voltages. This reduces the cost and size of the fuel cell power conditioning system.

Hybrid power relay

Hybrid power relay used for opening or closing electrical circuits, including an electrical contact having a mechanical movement, a semiconductor component in parallel with the electrical contact, and a control unit which in response to a logic input level causes the electrical contact to close (open) and the semiconductor component to be turned on. The control unit generates a contact-make signal for closing the contact, and a control signal that turn on the semiconductor component for a predetermined period of time. The control signal prevents the semiconductor component from being turned on after the predetermined period if the electrical contact fails to close so that the semiconductor component is undamaged. Also, the control unit generates a contact-break signal for opening the electrical contact, and turning on the semiconductor component before the electrical contact has opened by means of a control signal which terminates at the end of a second predetermined period after the electrical contact has opened.

Wireless intelligent host imaging, audio and data receiver

A system which marries a tethered, digital bus with image broadcasting to allow multiple, low-cost cameras to communicate with a host. This is done by using an external receiver on a tethered bus, and by putting much of the processing circuitry in the receiver, rather than the camera. The broadcasting can be either a NTSC / PAL type of analog broadcasting or a digital broadcasting technique. The camera can be made with low cost, readily available NTSC / PAL, other analog video components, or with readily available digital telephone components. The external receiver unit of the present invention does all the necessary data processing and compression to fit the available bandwidth of the bus to which it is communicating, and provides for a low cost and extensible method of inputting digital image data into a personal computer (PC) or other host.
