Disclosed is a method for reducing latency between two clock domains in a digital electronic device. The time between a write to a queue position and a corresponding read of the queue position is reduced by up to one clock cycle by including a delay in the time before first writing data to a First In First Out (FIFO) queue used to buffer and synchronize data between two clock domains. The two clock domains have the same frequency, but may be out of phase. Reducing the latency between the write and the corresponding read reduces the required size of the FIFO queue and also results in more efficient system operation.

A high speed, two-way serial interface with a scrambler and de-scrambler may be tested by sending a single word repeatedly through the scrambler to create a pseudo-random sequence. The pseudo-random sequence is then passed through the transmitter and looped back through the receiver of the serial interface. The pseudo-random sequence is then descrambled and compared to the input word. Since the input sequence is only a single word rather than a series of words, the comparison is very simple and capable of being performed within the serial interface itself without the need for external test equipment.

Products and processes for forming structural assemblies for building systems, such as window and door assemblies, are described. One such product includes an apparatus comprising a first end and a second end opposite the first end. A first leg and a second leg are disposed between the first and second ends. A first receiving groove is disposed in the first leg and forms a first pathway. A second receiving groove is disposed in the second leg and forms a second pathway.

A system includes a monitoring module, a congestion module, a modification module, and a communication module. The monitoring module monitors vehicles in a transportation network. The congestion module calculates a throughput parameter that is representative of a statistical measure of adherence to a movement plan by the vehicles. The modification module determines a confidence parameter representative of a probability that changing the original meet event does not reduce the throughput parameter. The modification module modifies the original meet event to an updated meet event when the confidence parameter exceeds a predetermined threshold. The communication module transmits the updated meet event to the yielding vehicle and/or the passing vehicle, for the yielding vehicle and/or the passing vehicle to receive the updated meet event from the communication module and change a speed of the yielding vehicle or the passing rail vehicle to arrive at the updated meet event.

Methods and systems for biographic scoring are disclosed. One system includes a biographic scoring module that applies one or more scoring rules to each of a plurality of biographic records to generate a score associated with each of the plurality of biographic records. The system also includes a result generation module that generates a report based on one or more scores generated by the biographic scoring module. The methods and systems disclosed can, in certain cases, reflect a likelihood that an individual associated with the biographic record is an unauthorized alien.

A lighting control for use with a lighting appliance includes a light sensor and a controller connected to the light sensor. Controller activates appliance when ambient light is greater than threshold. Threshold may be indicative of an interior of a closet of a room with a door of the closet open to the room and light available in the room. Controller may deactivate appliance once time has passed after appliance powered on. Lighting combination for use with power supply includes appliance including lighting source and control. Lighting control controls activation of lighting source. Controller has integrated memory for program to control controller. Controller may check to determine if light samples are increasing before activating lighting source. Start timer after light turned on. Turn off light when time out. Threshold learn mode based on sensed light before light on.

An adjustable mechanism for sliding panels, such as sliding windows and doors is disclosed. One embodiment comprises adjustable buttons that extend from a housing positioned in the sliding panel. The adjustable threaded buttons of the present invention provide a surface having reduced friction that extends from the bottom edge of a window or door and that can slide along a track supporting the window or door. In addition to providing a mechanism to facilitate horizontal sliding of a window or door, the adjustable buttons may be used to set the height of the sliding window or door as it sits in its frame.

The present invention is directed to systems and methods for automatically applying a tape, such as an adhesive, to a work-piece. According to one embodiment of the present invention, there is provided a system and method for a robotic tape applicator that includes a computer apparatus, a tape applicator apparatus, and an apparatus for holding a work-piece in registration with the tape applicator apparatus for tape application in response to programming data from the computer apparatus. Other components, such as a tape cutting apparatus, a splicing apparatus, adhesion promoter apparatus, and/or optical system can be added to assist and enhance the tape application process.
