The invention is an audio-video communication and answering system that synergistically improves communication between an exterior and an interior of a business or residence and a remote location, enables messages to be stored and accessed from both locally and remotely, and enables viewing, listening, and recording from a remote location. The system's properties make it particularly suitable as a sophisticated door answering-messaging system. The system has a DVMS module on the exterior. The DVMS module has a proximity sensor, a video camera, a microphone, a speaker, an RF transmitter, and an RF receiver. The system also has a computerized controller with a graphic user interface DVMS database application. The computerized controller is in communication with a public switching telephone network, and an RF switching device. The RF switching device enables communication between the DVMS module and the computerized controller. The RF switching device can be in communication with other RF devices, such as a cell phone, PDA, or computer.

A method and system for identification, tracking and locating in wireless communications and wireless networks. The method and system use reference and / or pilot signals that are present in wireless communications and wireless networks. The method and system might also use RTT, TOA and time-stamping measurements / techniques to determine one or more reference signals traveling time between the Base Station (eNB) or its functional equivalent and mobile device (UE) and or network device. Other wireless networks that do not use reference and / or pilot signals may employ one or more of the following types of alternate embodiments of present invention: 1) where a portion of frame is dedicated to the ranging signal / ranging signal elements; 2) where the ranging signal elements are embedded into (spread across) transmit / receive signals frame(s); and 3) where the ranging signal elements are embedded with the data. The method and system includes multi-path mitigations processor and multi-path mitigations techniques and algorithms which improve the track-locate accuracy. The method and system allow achieving increased accuracy by using multi-path mitigations processor and multi-path mitigations techniques and algorithms. The techniques of Digital Signal Processing and Software-Defined Radio are used.

A distributed voice user interface system includes a local device which receives speech input issued from a user. Such speech input may specify a command or a request by the user. The local device performs preliminary processing of the speech input and determines whether it is able to respond to the command or request by itself. If not, the local device initiates communication with a remote system for further processing of the speech input.

A wristband is assembled from a flexible preferably vinyl carrier and a preferably laminated ID label, the carrier having a panel portion and a strap portion with a snap closure located in a toe extension at the end of the carrier adjacent the panel. The strap has a series of holes, one of which is captured within the snap closure to attach the wristband to the wearer's limb. The laminated ID label has a pair of opposing slots, one of which slips over the strap to abut the panel and the other of which is captured by the snap closure to attach the label to the carrier. The panel portion has a relieved edge formed along its opposing sides which increases the comfort of the wristband as it is worn.

An illuminated suction apparatus including a hand-held surgical device combining a high-performance illumination waveguide with suction. This device would be useful in a wide array of various surgical procedures including open and minimally invasive orthopedics.

Actuatable assemblies fabricated by deposition of solidifying and non-solidifying materials are described herein. The actuable assemblies can be formed by co-deposition of a solidifying material and a non-solidifying material.

A train is driven by drive stations positioned along a track for frictionally contacting side plates on the train. The drive speed is controlled in response to sensors located at each drive station sensing a position of a wheel and a side plate for confirming a presence of the train. A start command is transmitted from the drive station driving the train to a second drive station downstream when a lead car is within a preselected distance from the second drive station. The drive station at the second drive station is quickly accelerated to a target speed for synchronizing the first drive station with the second drive station. After receiving the train, the second drive station then transmits a stop command to the first drive station for fast decelerating the drive station to a stop.

A stereo calibration method is proposed to calibrate an interface's shape and position when the measurement system is in one media and measures deformation and strain of an object that is submerged in a different media. After the interface's shape and position are modeled by parameters, an explicit model of object points as measurement is established taking account of refraction happening at the interface. Efficiency and convergence are assured by using measurement of object points to acquire initial estimates for refraction angles at the interface. Then, an optimization method is performed to get the optimized value of interface parameters. Last, based on the resulting interface parameters, 3-dimensional positions of object points in all the subsequent measurement could be reconstructed accurately. Therefore, the distortion induced by refraction in the measurement is corrected. Numerical simulations of the proposed calibration process confirm that it is both robust and accurate for a range of experimental conditions, even in the presence of Gaussian noise in the measurement.

The current invention is designed to improve the certainty of test-taker classifications in testing programs utilizing open-ended items. The current invention discloses methods to improve certainty in estimates of test-taker performance for all test-takers while using a minimum of scoring resources. The invention selectively allocates resources to scoring by ceasing to allocate scoring resources to test-takers whose performance has been determined with sufficient certainty, and by having an additional reader or readers score responses from test-takers whose scores are close to cutoff levels. The invention further increases precision of scores for test-takers near a cutoff by selectively allocating more reliable and accurate readers to score responses most likely to influence a test-taker's performance classification. Other scoring resources are also shown.
