A fall-protection apparatus comprising at least one connector that comprises a resonant-frequency-shifting inductive sensing unit that is configured to detect whether the connector appears to be connected to a first item and is further configured to detect whether the connector appears to be connected to a second, different item.

Fall-protection apparatus with multimodal inductive sensing

A fall-protection system including a harness and a fall-protection apparatus with a lifeline bearing a connector configured to be connected to the harness; and, a fall-protection monitoring system with a base unit and with at least one sensor module configured to sense a condition of the connector and to communicate a signal indicative of the condition of the connector to the base unit.

Fall-protection system with monitoring system

Techniques are described for monitoring and controlling fall protection equipment. For example, the techniques of this disclosure may be used to monitor the connection status of fall protection equipment, e.g., whether or not the fall protection equipment is connected to a support structure. The techniques described in the disclosure may determine whether the fall protection equipment is connected to a support structure based on changes in a resonant frequency of an electronic circuit of an inductive sensor within the fall protection equipment. The inductive sensor may be formed from sets of one or more coils, where a first set of one or more coils and a second set of one or more coils are wound in opposite directions.

Fall protection equipment having inductive sensor for connection status and control

A sensor comprising a thin film photovoltaic pixel is fitted with optics to provide a field-of-view for the sensing of persons, or other objects, entering or exiting said field-of-view. When a person enters the field-of-view, a processor may sense such entry, then provide signals to other electronic apparatus indicative of such an event.

Object sensor

3D stereoscopic viewing enabled by the use of a fast switching speed LCD panel, dynamic backlight, and low cost glasses. The system utilizes an LCD panel with an LED backlight and wavelength selective glasses to isolate each channel by color. The system is based on alternating left and right image frames on an LCD panel. The left and right frames are illuminated by two slightly different red-green-blue light sources that are synchronized sequentially. The light sources are designed to emit light of different spectral composition. The viewer wears glasses where the left lens or filter passes only the spectrum of light used for the left channel of data, and the right lens or filter passes only the spectrum of light used for the right channel of data.

Stereoscopic 3D display device

A display apparatus includes an liquid crystal display panel having a frame response time of less than 5 milliseconds, drive electronics configured to drive the liquid crystal display panel to black between images that are provided to the liquid crystal display panel at a rate of at least 90 images per second, and a backlight positioned to provide light to the liquid crystal display panel. The backlight includes a right eye solid state light source and a left eye solid state light source capable of being modulated between the right eye solid state light source and a left eye solid state light source at a rate of at least 90 Hertz.

A scanning backlight for a stereoscopic 3D liquid crystal display apparatus includes a light guide having a first side and a second side opposite the first side, and having a first surface extending between the first and second sides and a second surface opposite the first surface. The first surface substantially re-directs light and the second surface substantially transmits light. A plurality of first light sources are arranged along the first side of the light guide for transmitting light into the light guide from the first side and a plurality of second light sources are arranged along the second side of the light guide for transmitting light into the light guide from the second side. The first light sources are divided into a plurality of first groups and the second light sources are divided into a plurality of second groups, each first group having a corresponding and opposing second group, and the first groups and second groups are selectively turned on and off in a particular pattern where only the first group or corresponding and opposing second group selectively transmits light into light guide at one time.

A method for displaying an indication of data collected via a wireless network sensor involves processing the collected data to generate reports. The wireless network sensor includes a plurality of sensors for detecting events occurring proximate the sensors, a processor for receiving and processing data from the sensors, and a wireless transmitter for wirelessly transmitting data. The method displays an indication of parsed events, episodes, vectors, links, and paths based upon the received data. Another method displays a representation of a location of each sensor in the wireless network sensors in a monitored environment and information related to data collected via the sensors.

Display of information related to data collected via wireless network sensors

An apparatus for processing data collected via a wireless network sensor includes modules for receiving and processing the data. The wireless network sensor includes a plurality of sensors for detecting events occurring proximate the sensors, a processor for receiving and processing data from the sensors, and a wireless transmitter for wirelessly transmitting data. The apparatus also includes modules for parsing events, episodes, vectors, links, and paths based upon the received data. The paths can be used to generate a representation of traffic patterns in a space monitored by wireless network sensors.

Apparatus and method for processing data collected via wireless network sensors

An LCD device with 3D and 2D sections. The device includes an LCD panel, a light guide with a backlight, and an embedded 3D-2D film stack positioned between the LCD panel and the light guide. The 3D and 2D sections provide for simultaneously viewing visual content in 3D and 2D formats. The device can also include a frame providing a barrier between the 3D and 2D sections and can include other features to enhance the display.
