A system and a method for creating a stable and reproducible interface of an optical sensor system for measuring blood glucose levels in biological tissue include a dual wedge prism sensor attached to a disposable optic that comprises a focusing lens and an optical window. The disposable optic adheres to the skin to allow a patient to take multiple readings or scans at the same location. The disposable optic includes a Petzval surface placed flush against the skin to maintain the focal point of the optical beam on the surface of the skin. Additionally, the integrity of the sensor signal is maximized by varying the rotation rates of the dual wedge prisms over time in relation to the depth scan rate of the sensor. Optimally, a medium may be injected between the disposable and the skin to match the respective refractive indices and optimize the signal collection of the sensor.

A control system for managing a heating, ventilating and air conditioning (HVAC) system based on occupancy of an area is provided. The occupancy may be determined by anticipated programming based on time of day zoning, and / or by actual sensed occupancy. In the later, the control system includes an occupancy sensor that communicates with a programmable thermostat. The occupancy sensor is disposed in the area and senses a state of occupancy of the area. The programmable thermostat instructs the HVAC system to adjust the temperature of the area within the structure based on the state of occupancy of that particular area to enhance occupant comfort and energy efficiency. The thermostat may also include programming modes or scripts that may be run to adjust operational control when abnormal occupancy conditions are sensed. Controllable dampers may also be used by the thermostat to achieve micro zoning control of the HVAC system.

An intelligent medical vigilance system that observes and analyzes, and, only in the event of a clinically significant negative condition, notifies and reports the event to the care staff utilizing the hospital's existing nurse call system. The device includes a bedside unit connected to a pad or coverlet with a sensor array (placed under the patient) and also to an existing hospital nurse call system via an interface. Within the physical bedside unit are a signal processor and an alarm processor that measure data and evaluate whether a clinically significant event is occurring. The bedside unit is a wall-mounted unit with a display that becomes active when an alarm condition is enabled. The sensing pad or coverlet is a thin, piezoelectric film, or other similar sensing technology, with an array of sensors sheathed in soft padding and is not directly in contact with the skin of the patient. The nurse call feature is made up of hardware, software and cabling to connect to the nurse call system already installed in the hospital or care facility. The monitoring system can also be installed in vehicles to monitor operator physiological conditions.

Web pages are displayed with a simultaneous overview and magnified view. An indicator can show the portion of the overview in the magnified view. Both views can be shown, one above the other, across the full width of the same screen. A user can select between such a split view and another view, including an overview-only view, a magnified-only view, and a view in which selected text is laid out to fit the width of the magnified view. Navigational input can directly move the layout in the magnified view or the cursor, and can scroll both the overview and magnified view. The magnified view can display text with antialiased fonts designed for its resolution. The magnified view can be made to function like a magnifying glass. The width of text in multicolumn layouts can be limited to fit the width of a view window, such as the magnified-view.

The electrolyte inside a lead and acid battery is inaccessible and measurements of the voltage across a battery's terminals do not necessarily give a good indication of the future performance of a battery. Furthermore, although the state of charge of a battery can be determined from measurement of the voltage across its terminals, these measurements will be misleading unless they are taken when the battery is in equilibrium. Accordingly, the present invention proposes a battery monitor which takes measurements from a battery and is configured to detect one or more types of event affecting the battery life and to subtract a predetermined amount from a life counter representing the remaining available life of the battery, each time such an event is detected. The monitor is also configured to calculate the state of charge of the battery, but only when the battery is in equilibrium.

A passport and identification card reader minimizes the time and effort required for an operator to read / scan a passport or piece of identification. An immigration official, for example, can slide a passport into place with one hand while tending to other important security activities with the other hand. Once in place, the passport will be automatically detected and read. Numerous passports bound together by a traveler with multiple visas can be held flat in place and accurately read, even with one hand, despite the natural tendency of the passport(s) to return to a closed position.

In addition to determining orientation, a method and associated instrument provide a non-gravity acceleration vector of the device.
