An electromechanical toilet leak detector comprises first and second enclosure portions. An adhesive structure disposed on the second enclosure portion, the adhesive structure in use for being removably adhered to the porcelain outer surface of a flush toilet. One of the first and second enclosure portions includes a groove that mates with a lip provided by the other of the first and second enclosure portions to provide a substantially water-resistant seal therebetween. A vibration sensing transducer disposed between the first and second enclosure portions generates a signal responsive to vibration generated by the toilet due to water inflow turbulence.

Self-stick resonant enclosure that responds to flush toilet fill valve water inflow vibration

Water is conserved by detecting unintended inflow of water into the tank of a flush toilet. A sensor acoustically and/or vibrationally coupled to the flush toilet detects sound and/or vibration generated due to turbulence in water flowing into the toilet tank. An electronic circuit analyzes the sensor output to detect cyclical water inflow not intended by a user. The electronic circuit generates an alert such as an audible and/or visual indication that the toilet is leaking.

Detecting unintended flush toilet water flow

A battery pack assembly is provided for supplying electrical power to an electronic device, such as an electronic receiver of an animal confinement system. The battery pack assembly is removably insertable within a receptacle of the electronic receiver to electrically connect a battery contained within the battery pack assembly to internal electronics of the electronic receiver.

A two-piece portable, self-contained tympanic thermometer temperature measuring system includes a measuring unit and a base unit. The measuring unit can be ergonomically designed as a compact, pencil-shaped, easy to hold unit that includes a removable sensing module that interfaces with the base unit and/or other host via digital signaling. All analog circuitry can be self-contained within the sensor module, and the sensing module circuitry components may be potted with thermally conductive epoxy to reduce variations due to differences in component temperatures. The sensing module casing may be made out of a conductor to provide electromagnetic field isolation. The sensing module can include a microcontroller that communicates with a microcontroller in the base unit via a removable modular 4-conductor telephone handset cord. The measuring unit preferably has the capability to measure the amount of pressure it is applying to the patient's ear&mdash;and thus, the ability to sense when it is in position and has sealed the patient's outer ear canal. Temperature measurement can be performed automatically and/or inhibited in response to this pressure sensing.

Tympanic thermometer with modular sensing probe

In a tympanic thermometer probe cover including a film, an additional, substantially non-stretchable structure is mechanically coupled to the film in the area where the probe contacts the film. This additional structure is designed so that it does not occlude infrared radiation from reaching the probe while maintaining the portion of the film over the probe distal end in a prestretched, wrinkle-free condition and preventing that portion of the film from stretching further. The structure may comprise a concentric registration ring that is adhered to the film. The registration ring includes a central open hole portion through which infrared radiation may pass without occlusion. The ring self-adheres to the film, maintaining the film in a prestretched, wrinkle-free condition. When the probe cover is applied to the probe, the probe contacts the ring. Since the ring is substantially non-stretchable, the ring prevents the film from further stretching over the probe. The film and the ring may be fabricated as a single polyethylene, silicone, foam or other infra-red transparent window-type material.

Tympanic thermometer disposable probe cover with further stretching

A disposable probe cover for an electronic tympanic ('ear') thermometer is made of closed-cell foam that is laminated with a sheet of high density polyethylene plastic film substantially transparent to infrared radiant energy. The probe cover is hollow, defining a central passageway that accepts an oversized probe and can potentially accommodate a variety of different probe configurations. The foam construction allows the probe cover to stretch over the oversized probe--retaining the probe cover on the probe during use. The foam construction also allows the probe cover to deform when inserted into a patient's ear--sealing the patient's ear canal to prevent external heat and light from affecting the measurement, and providing a high degree of cushioning and comfort not available in any prior disposable probe cover design. The film laminate and foam provide a barrier that is impervious to germs, fluids and other secretions--further reducing the already low risk of cross-contamination. The probe cover design facilitates accurate, repeatable measurements using a temperature measuring instrument based on receiving and analyzing the radiant infrared heat energy emitted by the tympanic membrane (eardrum).
