Pet animal collar for health & vital signs monitoring, alert and diagnosis

A collar for pet animals may have sensor elements remotely actuatable to measure vital signs of the animal (such as respiration, pulse, temperature and movement) and a processor that can interpret the results of multiple vital sign readings. A two way communication device alerts the pet owner, veterinarian or authorities. A veterinarian can remotely take a particular vital sign measurement when alerted. The sensor elements embedded in the collar's band has at least one elastic pin extending toward the animal's neck to gather data processed on the collar or remotely. To improve STN ratio, an elastic layer may absorb noise from friction due to movement of the animal's head. The collar may adjust the tightness of the band for taking vital sign readings. For example pump may injects air through a tubular compertment running along the circumference of the band. A safety mechanism may release the collar.

Method and Apparatus for Controlling and Powering an Electronic Accessory from a Mobile Digital Device

Various energy harvesting and control techniques are used to power and control electronic accessories from the audio output channels and microphone input channel of mobile digital devices while preserving audio input and output functionality. One technique uses one of the stereophonic audio channels to generate power, and the other in conjunction with the microphone jack to enable bi-directional communications while preserving audio input and output. Another technique allows a low powered electronic accessory with bi-directional communications to be supported while simultaneously supporting audio input & stereo output. These techniques facilitate the ability to play music, narration and instruction and to receive oral responses and instruction with no perceived loss or gaps, even while using the audio jack of a mobile digital device to harvest energy and bi-directional communication.

Inductive communication system and method

A system and method communicate signals between a portable unit and a communications system. The portable device communicates with a base unit using inductive coupling. The base unit is further connected to a wider communication system such as a telephone network. Multiple, orthogonally arranged transducers are used in the base unit to provide a more complete magnetic field and to prevent mutual inductance nulls which are otherwise present in a magnetic field. The use of short-range inductive coupling minimizes the power requirements and limits interference with other sources. The inductive coupling may also be used to recharge a battery in the portable device.
