Dimming and mixing light emitting diodes using reduced pulse widths
A dimming and color mixing apparatus for light emitting diodes (LEDs) combines constant current distribution with reduced pulse widths. A current source provides a constant source of LED drive current to at least a pair of switches under command of an LED controller. A predefined fraction of the LED rated current that will ensure uniform light output between the LEDs is selected as a minimum drive current to be supplied from the constant current source. The LED controller causes the switches to provide alternating pulses between at least two channels of LEDs according to a switching rate for color mixing, and the current source decreases the LED drive current linearly for dimming. For dimming levels below the minimum drive current, the LED controller decreases the pulse widths in conjunction with the decreased drive current. In one arrangement, for each LED channel the percentage of a duty cycle for the pulsed current is less by a factor of 10 than the percentage of the relative current from the constant current source. The decreased pulse widths lead to increased peak current driven to the LEDs from the constant current source and helps avoid nonuniform light emission when dimming and color mixing the LEDs. |

Hybrid HTTP and UDP content delivery
A hybrid HTTP/UDP delivery protocol provides significant improvements for delivery of video and other content over a network, such as an overlay. The approach is especially useful to address problems (e.g., slow startup times, rebuffering, and low bitrates) for HTTP-based streaming. In general, the protocol has two phases: an HTTP phase, and a UDP phase. In the HTTP phase, the client sends an HTTP GET request to a server. The GET request contains a transport header informing the server that the client would like to use UDP-based transfer over the protocol. The server may refuse this mode and continue in ordinary HTTP mode, or the server may respond by sending an empty response with header information informing the client how to make the connection to enter the UDP phase. In the UDP phase, the client initiates a connection and receives the originally-requested content over UDP. |

Current operative analog to digital converter (ADC)
An analog to digital converter (ADC) senses an analog signal (e.g., a load current) to generate a digital signal. The ADC operates based on a load voltage produced based on charging of an element (e.g., a capacitor) by a load current and a digital to analog converter (DAC) output current (e.g., from a N-bit DAC). The ADC generates a digital output signal representative of a difference between the load voltage and a reference voltage. This digital output signal is used directly, or after digital signal processing, to operate an N-bit DAC to generate a DAC output current that tracks the load current. The digital output signal provided to the N-bit DAC is an inverse function of the load current. The ADC is operative to sense very low currents (e.g., currents as low as is of pico-amps) and consume very little power (e.g., less than 2 μW). |

Flexible system of small-scale linear parabolic solar concentrators for power generation and dehydration
The invention relates to a solar energy collection system that uses linear parabolic concentrators designed on a small scale and with a modular configuration that allows optimum usage of solar collection surface area in places such as the roofs or flat roofs of factories or shops where space is generally small or irregular. The solar collector is coupled in rows actuated by a fully autonomous system for electronically controlling solar tracking, the operation of which is based on an algorithm programmed in a microcontroller. An autonomous solar tracking system can efficiently control two parallel rows with a pre-defined number of solar concentrators, as well as automatically detecting the presence of impurities on a reflecting radiation surface for the maintenance thereof. The thermal energy produced is harnessed by a heat exchanger, the operation of which is based on conduction, convection and radiation for dehydration uses. |
