International Classification:

H01F 38/14

US Classification:

307104

Abstract:

Disclosed herein are systems and methods for wirelessly transmitting power to receivers that are freely mobile, such as power receivers for sensors attached to animal experiments. An example transmitter includes a resonator including a generator and transmitter coil, an initial drive signal generator that removes the generator from an ‘off’ state thereby causing the transmitter coil to create an alternating magnetic field that oscillates within a threshold of a resonant frequency of the generator, a phase detector that receives a signal from a receiver coil receiving power via the magnetic field, and a transition module that switches from the initial drive signal to a drive signal generated based on output from the phase detector. An example wireless power receiver has three turns of wire, one on each axis, around a ferrite plate, the outputs of which are connected in parallel to produce a combined output power signal.

Abstract:

An apparatus is provided for cooling a substrate. The apparatus includes a chamber configured to receive the substrate. The chamber comprises multiple sidewall sections surrounding the substrate and oriented in a vertical direction substantially parallel to a vertical side surface of the substrate. The apparatus also includes at least one gas inlet port on a first side wall section of the chamber. The gas inlet port is configured to introduce a cooling gas into the chamber in a lateral direction parallel to top and bottom surfaces of the substrate. The apparatus further includes at least one gas outlet port on a second side wall section of the chamber located substantially opposite of the first side wall section of the chamber with the substrate disposed therebetween. The gas outlet port is configured to conduct at least a portion of the cooling gas out of the chamber along the lateral direction.
