Method, system and program product are provided for monitoring coolant within a cooling system designed to provide system coolant to one or more electronics subsystems. The monitoring technique includes employing at least one pressure transducer to obtain multiple pressure measurements related to an amount of coolant within an expansion tank of the cooling system, and determining a rate of volume change of coolant within the expansion tank employing the multiple pressure measurements. Successive...

Disclosed is a fluid level gauge for sensing the level of fluid in a dispenser. The level gauge includes an inlet port communicating with the fluid and a check valve in communication with the inlet port. The check valve includes a membrane which allows air to pass. The level gauge further includes a pressure sensor in fluid communication with the check valve. The fluid level gauge may be used in connection with a beverage dispenser.

A tube-mounted inclined optical flat for improving the stealth capability of an optical aperture is disclosed. The optical flat has a light-absorbing finish on its rear surface, and is mounted in front of existing instrument optics. The light from the scene being viewed passes through the optical flat and is undistorted. Any light that is reflected from the optical flat is absorbed by the light-absorbing tube. Light that enters the distal end of tube is absorbed in the same manner. Any light ent...

Circuit system and method for receiving and demodulating signals to a tire pressure monitoring system. The circuit comprises a demodulator for receiving an input signal modulated at a first frequency and demodulating the input signal so that information can be extracted from the input signal at a second frequency lower than the first frequency. The circuit further comprises a microprocessor, operating at a clock rate selected to extract information from the demodulated signal at the second frequ...

A method and apparatus are provided for facilitating compliance with a medication regimen by a user. The method includes the steps of providing the user with a medication dispensing unit for dispensing medication to the user and a wireless transceiver operatively coupled to a controller of the medication dispensing unit, downloading a set of instructions for controlling the medication unit from a server to the controller of the medication dispensing unit through the wireless transceiver and down...

A processor implemented monitoring system includes a sensor coupled to the processor for sampling a physiological parameter of a subject which may comprise a subject unique identification parameter. Also coupled to the processor is a physical location determining device. Subject location as well as parameter status data are input to the processor which is programmed to determine whether the parameter and/or location data falls within prescribed boundaries stored in a memory. Upon determination o...

The invention relates to an image transmission system for endoscopes and similar viewing tubes with at least one rod lens and at least one additional lens system. In order to produce an image transmission system of simple and economical construction, it is proposed in accordance with the invention that the minimum of one rod lens should be constructed as a plano-convex lens whose length corresponds to the curvature radius of its convex terminal surface. In addition, the invention relates to a pr...

In a preferred embodiment, a machine for milling doors and/or drawer fronts, including: apparatus to horizontally clamp a door or drawer front to a horizontal movable table; apparatus to remove vertically disposed scribe pins from the door and/or drawer front, backs of the vertically disposed scribe pins defining a position of a frame to be spaced from the door and/or drawer front by a reveal; points disposed at the lower end of the vertically disposed scribe pins, flush with the backs, the poin...

A method in a sheet metal working center, wherein a sheet secured to mounting member of a moving carriage arrangement is transferred in accordance with a predetermined program substantially in XY orthogonal coordinates in the main plane of the sheet so that machining of the sheet may be carried out by multiple machining units. At least two of the machining units are placed in the sheet metal working center and have separate XY orthogonal coordinates, and directions X of the separate XY orthogona...

A fluid container includes a vessel for holding a fluid, a marker element, and a scale element. The scale element has a scale for indicating a total quantity of the fluid. The marker element and the scale element are adjustable relative to each other to enable an adding up of amounts of fluid and thereby indicate the total quantity of the fluid. The marker element and the scale element are held together by magnetic force and may be detached from each other.
