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.

One aspect of the present invention is generally directed towards a system and method of tuning a transducer for transmitting and receiving a wireless signal. In an illustrative embodiment, a single transducer is coupled to a first or second circuit for either transmitting or receiving, respectively. Generally, electrical characteristics of the first circuit are adjusted to increase a magnetic field generated by the transducer. Conversely, electrical characteristics of the second circuit are adjusted to increase a signal generated by the transducer for receiving a magnetic field. Accordingly, a single transducer device can be tuned for either transmitting or receiving a corresponding wireless signal.

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.

A system for monitoring vital signs of a pet animal comprises an annular band, an accelerometer configured to measure at least one of resting patterns, activity patterns, movement patterns, position patterns relating to, for example the pet animal relieving itself, lameness and scratching, and a non-accelerometer sensor configured to measure at least one of the following non-accelerometer-measured bioparameters of the pet animal: temperature, pulse rate, respiration rate. One or more processors are configured to receive sensor output data and reference data concerning the measured bioparameters of the pet animal or of a population of the pet animal, and determine a suspicion of a specific medical condition by: (i) scoring at least two bioparameters and comparing a cumulative score to a threshold cumulative score or to a threshold cumulative range; or (ii) identifying an abnormal pattern. The processor(s) may send an alert if at least one specific medical condition is suspected.

A low-power implant system. The system includes an implant for implantation into a person, such as a cochlear implant or a middle ear implant. The implant is capable of communicating with a device via transmission of ultra wideband pulses. The device may be adapted to be worn external to the person, or may be a second implant. So as to conserve battery power, the transmitted ultra wideband pulses may have a low duty cycle of approximately 1/1000 or less. Power savings may also be realized by using time-gating amplifiers in the implant and/or device receiver.

Contents of one or more received messages can be analyzed to determine whether a transceiver device generating the inductive field has already been programmed with a unique communication code. If not, bidirectional communications can be established to program the transceiver device with a unique communication code over an inductive link. Orientation or position of a transceiver device can be used to initiate a process for programming a communication code. Generally, the communication code can define a unique relationship between two or more transceiver devices.

A magnetic communication system includes a transmitter have a single coil transducer, and a receiver having a three orthogonally oriented coil transducers. The signal processing circuitry in the receiver adjusts the phases of the signals received by the three transducers to produce signals which are in-phase. The signals are then summed to provide an output signal from the receiver. The processing circuitry adjusts the phases of the incoming signals either serially or in parallel. Transmissions from the receiver to the transmitter are also phase adjusted in accordance with the same adjustments used in reception.
