摘要:
A sensing system for a floating pool system for detecting and alerting a user of disturbances and detecting various levels and releasing chemicals into a liquid medium. The system comprises a controller that can comprise a wireless communication module and at least one sensor, and a receiving device can be configured to receive a signal from the wireless communication module. The controller can comprise at least one tilt sensor that is generally in an open position and closes with a waking event. The controller sends a message to the receiving device when a waking event occurs, alerting the user to a disturbance and possibly dangerous situation.

Many people do not have a physical feeling for what normal and abnormal blood pressure levels mean in relation to the forces exerted on the heart and blood vessels. A blood pressure simulation apparatus provides human subjects a means to physically feel simulated blood pressure levels through tactile feedback. Both normal and abnormal blood pressure cycles are simulated. Interfacing of the apparatus to an electronic blood pressure monitor is provided.

Due to the presence of various environmental condition detectors in the home and businesses such as smoke detectors, carbon monoxide detectors, natural gas detectors, etc., each having individual but similar sounding alarm patterns, it can be difficult for occupants of such dwellings to immediately determine the specific type of environmental condition that exists during an alarm condition. The present invention comprises an environmental condition detector using both tonal pattern alarms and pre-recorded voice messages to indicate information about the environmental condition being sensed. Single-station battery-powered and 120 VAC detectors are described as are multiple-station interconnected 120 VAC powered detectors. The pre-recorded voice messages describe the type of environmental condition detected or the location of the environmental condition detector sensing the condition, or both, in addition to the tonal pattern alarm. Provisions are made for multi-lingual pre-recorded voice messages.

An ambient condition detector includes a time delay function whereby a user initiates a functionality test of the detector and has time to move away from the vicinity of the detector before a potentially hearing damaging, audible report is issued from the detector under test. Multiple ways to set the time delay interval are included in the various embodiments. The sensors of the ambient condition detector may include fire sensors, smoke sensors, gas sensors, motion sensors, vibration sensors and multiple combinations of these sensors.

The herein disclosed IC engine relies on air injection for ignition instead of Otto cycle spark or Diesel cycle fuel injection. One or more adjacent cylinders are connected by a valve, which is opened near the end of their compression strokes so that high-pressure air can inject into the cylinder containing the air fuel mixture, and induce detonation ignition at top dead center. During expansion the cylinder-connecting valve remains open and provides equal pressure on both cylinders, which is substantially higher than possible in Otto cycle. Constant volume heat addition makes this engine also more efficient than Diesel cycle. The absence of spark ignition or high pressure fuel injectors make this engine more economical, more reliable, and scalable down to very small size unlike Diesel fuel injectors which cannot meter small quantities and eliminate the Diesel cold starting problem. Engine can serve as reactor for generating high temperature hydrogen to power high temperature fuel cells.

A system and method for managing a value of a descending register of a postal security device (PSD) in accordance with a guarantee is disclosed. Mailing data including a guarantee rate, and a public rate of postage disbursed for a mailpiece franked under terms of the guarantee, can be received. The public rate and the guarantee rate can be compared, and if the public rate is equal to or less than the guarantee rate, postage funds can be downloaded from an account corresponding to a lessee of the PSD.

Imaging systems, methods, sensor pods, and vehicles having imaging systems. An imaging system can be coupled to a vehicle and can comprise: a plurality of imaging sensors with multiple spectrums; and a processing unit configured to generate an image model in substantially real-time by: warping, fusing, and stitching images; and two or more displays coupled to the processing unit such that the two or more displays can simultaneously each show a different portion of the image model, and such that a user can manually calibrate via the processing unit at least one of the warping, fusing, or stitching. In some imaging systems, imaging sensors are coupled at different elevations relative to a ground vehicle. The present sensor pods can comprise a housing; two or more first imaging sensors having a first spectrum; and two or more second imaging sensors having a second spectrum that is different than the first spectrum.
摘要:
The blood pressure level in humans is a vital health parameter, yet the vast majority of people do not have a physical feeling for what normal and abnormal blood pressure levels mean in relation to the forces exerted on the heart and blood vessels. A blood pressure simulation apparatus is described which provides human subjects a means to physically feel simulated blood pressure levels through a tactile interface. Both normal and abnormal blood pressure cycles are simulated. Interfacing of the apparatus to an electronic blood pressure monitor is provided.
