摘要:
A sensor capable of being adapted to sporting protective gear for sensing forces or vibrations encountered by the protective gear. The device senses the forces and delivers a signal proportional to the sensed force into a circuit for determining the accumulative force encountered by the protective gear over a period of time. The determining circuit is capable of decrementing the accumulated force according to a predetermined source-time pattern in order to allow the user of the sporting protective gear to recover. The accumulated force is sensed and as decremented is suitably displayed.

This invention provides a highly portable device for counting athletic activities of a repetitive nature, e.g., pool laps swum, track laps run, pushups, situps, etc. The device has a mat-like body flexible enough to be rolled up and carried in a handbag. It is comprised of: (1) a watertight upper section containing a weight for anchoring the device during use, battery and circuit means for powering a lap counting electrical circuit, (2) a middle section for displaying an athletic activities card and (3) a watertight lower section containing a lap count display and a touch pad which operates the lap counting electrical circuit in a manner such that the display count advances by one for each touch of the pad.

A storage tank level monitoring apparatus and method for determining fluid levels in a storage tank. The apparatus of the present invention includes a magnet coated with rubber for holding a pivotally mounted housing to the interior of the storage tank and an ultrasonic transducer contained within the housing for generating acoustic pulses and for receiving reflections of the acoustic pulses for producing an analog signal proportional to the reflections, a string carrying a number of reference disks vertically oriented below the housing for producing a series of reflected acoustic signals from each reference disk, and a processor connected to the ultrasonic transducer for activating the transducer and for analyzing the reflected pulses for calibrating the apparatus for environmental changes in the atmosphere above the stored fluid and for determining the level of the stored fluid in the tank. The method of the present invention includes the steps of receiving reflected pulses from each reference disk only during certain window time intervals and to calibrate the system by adjusting for environmental conditions between the transducer and the fluid level.

A networked light for illumination and intercom for communications in a single housing, with voice command and control, hands-free. The system in a housing configured to conventional looking lamp, bulb, fixture, lighting devices, suitable for a direct replacement of conventional illuminating devices typical found in homes or buildings. A network of such voice command and control systems may be further monitored and controlled from a base station that facilitates programming, communications, and higher functionality therebetween. The system provides speech recognition for powering on and off, dimming, brightening, and adjusting the lighting to preset, night and emergency settings. The voice recognition command controls the intercom to be active and attentive to requests, connecting two or more locations within a home or building structure, for speech exchanges in communications, via radio frequency transmitting and receiving of signal messages between the individual light and intercom system devices within a network of devices.

A monolithic compressed-gas dryer including in series: an inlet chamber, a precooler/reheater chamber, an evaporator chamber, and a sump chamber. The chambers are welded together to form columns where at least one column has a filtration chamber. Further provided is a gas outlet. The system creates a first and second set of heat transfer passages where refrigerant passes through the second set in a heat exchange relationship in a direction perpendicular to incoming gas passing in the first set. The filtration chamber conducts chilled gas from the first set to a third set of heat transfer passages. The third set extends through the precooler/reheater in heat exchange relationship with the first set. Chilled gas passes in heat exchange relationship in a direction perpendicular to the incoming gas so that the incoming gas chilled in the evaporator exchanges heat with the incoming gas in the precooler/reheater.

The present invention provides a method and process for effectively purging desiccant air dryer systems from moisture load, by a ‘deep cooling’ regeneration means with the use of a primary high heating and a secondary low heating blower purge air flows, a heater discharge temperature set point, and a bottom area bed temperature of a vessel containing desiccant. The system of an improved heat regenerating desiccant compressed air dryer having means to terminate heating operations as well as cooling and dry purge operations allowing for the newly regenerated tower vessel to come back on-line for a compressed air drying cycle without negative effects of dew point bumps and outlet heat spike. Such dryer system delivers a high confidence of dried compressed air while saving energy, unnecessary cycling of heater and contactors and time.

A networked visual and audible alarm light system and method with voice command control and base station having alarm for smoke, carbon monoxide, and gas provides illuminating LEDs, audible alerts, a base control, and a voice command control. The system detects and alerts to smoke, carbon monoxide, and gas. Multiple light fixtures audibly and visually alert in different colors, patterns, and intensities, dependent on the type of event detected. A network of systems are monitored and controlled from a base station that facilitates communication therebetween. The system provides speech recognition for powering on and off, dimming, brightening, and adjusting the lighting; including presets and emergency situations. The voice recognition command controls lighting choices, and can silence or suspend alarm-state by verbally commanding SHUT OFF. The base station monitors and programs individual LED and detecting devices that create a network within a home or structure to manage lighting and security.

摘要:
The present invention relates to a method and apparatus for effectively reducing/eliminating oscillation of over and under shoot of superheat and refrigerant feed in an evaporator of compressed refrigerant of a gas/air dryer system. The feed makes use of a plurality of refrigerant expansion valves, sized in scaled manner, and adjusted inversely to the size of each, affording exact feed requirements to the evaporating vessel heat exchange. The system uses superheat feedback to respond rapidly or slowly to fill need for large or modest injections leading to stable, balanced operations. The operations ‘level-out’ to a smooth, even output of the gas/air dryer dew point temperature, relatively close to the dew point seat point without falling into an endless loop oscillation. The feed delivery of staged injection meters expanded refrigerant to demand while tracking superheat.
摘要:
An improved leak detection float system for use in underground storage tank containing fuel wherein the float system utilizes an elongated hollow test probe extending downwardly into an underground storage tank and into the fuel stored therein. A microprocessor is contained in an upper compartment of the test probe along with control electronics. A rod is centrally affixed in the lower portion of the test probe and a float is disposed around the rod, but within the test probe so as to float on the surface of the fuel. The float uses tapered edges to minimize offset error due to surface tension. An excitation transducer is placed above the float on the rod which produces vibrational waves down the rod having a predetermined frequency, power, and duration. The vibrational wave breaks the surface tension existing between the float and the fuel so that the float can obtain a position within the fluid based upon the buoyancy of the float in the fluid. The breaking of the surface tension by vibrational wave minimizes any offset between the float and the fluid caused by surface tension.
