A device for charging at least one rechargeable battery of a battery-operated surgical instrument that comprises a sealed container operable to enclose and create a microbial seal around the battery. The sealed container permits surgical sterilization and inductive charging of the battery while the battery is enclosed therein. The device further comprises an inductive charging assembly having a power receiver sub-assembly inside the sealed container and electrically coupled to the battery whereby the power receiver sub-assembly is operable to receive electrical power inductively from outside the sealed container and to charge the battery electrically coupled to the power receiver sub-assembly. A power supply is disposed outside the sealed container and supplies power inductively to the power receiver sub-assembly through the sealed container such that the sealed container is not structurally breached.

There is provided a planar inductive battery charging system designed to enable electronic devices to be recharged. The system includes a planar charging module having a charging surface on which a device to be recharged is placed. Within the charging module and parallel to the charging surface is at least one and preferably an array of primary windings that couple energy inductively to a secondary winding formed in the device to be recharged. The invention also provides secondary modules that allow the system to be used with conventional electronic devices not formed with secondary windings.

The wireless power transmission is a system for providing wireless charging and / or primary power to electronic / electrical devices via microwave energy. The microwave energy is focused onto a device to be charged by a power transmitter having one or more adaptively-phased microwave array emitters. Rectennas within the device to be charged receive and rectify the microwave energy and use it for battery charging and / or for primary power. A communications channel is opened between the wireless power source and the device to be charged. The device to be charged reports to the power source via the channel a received beam signal strength at the rectennas. This information is used by the system to adjust the transmitting phases of the microwave array emitters until a maximum microwave energy is reported by the device to be charged. Backscatter is minimized by physically configuring the microwave array emitters in a substantially non-uniform, non-coplanar manner.

A sequential power transmission between a portable user-carried battery and first and second independent accessories. At least one primary inductive coupling coil is mounted on an article of apparel worn by the user, so as to place a primary coil adjacent a first intermediary inductive coupling coil on the first independent accessory. The energizing of the first intermediary coil energizes a second intermediary coil on the first independent accessory. The second intermediary coil, when energized, energizes a secondary coil on the second independent accessory for powering the use, including the charging of the batteries of that accessory.

There is provided an apparatus for battery life estimation comprising an energy harvester; an energy storage apparatus, connected to the energy harvester, the energy storage apparatus representative of a unit of measure; a battery for receiving energy from the storage apparatus; and a processor for monitoring the energy provided by the storage apparatus, monitoring energy provided to the battery by other charging apparatus and monitoring the energy being delivered by the battery; wherein the processor calculates the remaining life of the battery based on the number of energy storage apparatus units that are provided to and delivered from the battery.

A battery charging station is equipped with radio frequency power transmitters, induction power transmitters, and ultrasound power transmitters so as to concurrently charge electronic devices. The battery charging station is operable to network the electronic devices through wireless communication. In this regard, the battery charging station may coordinate or arrange the radio frequency power transmitters, the induction power transmitters and / or the ultrasound power transmitters so that the resulting power transmission from the battery charging station to one or more intended networked electronic devices may be maximized. The battery charging station may wirelessly communicate with the electronic devices for device networking. The networked electronic devices may be connected to a computer network for various network services such as, for example, network advertising and software downloading or uploading. Both direct and in-direct device-to-device communication may be supported among the networked electronic devices. The battery charging station maintains data communication during battery charging.
