    Abstract: A wireless charging system includes a power transmitting device and a power receiving device. In the transmitting device, a transmitting coil converts a drive signal from a drive signal circuit into an alternating magnetic field. In the receiving device, a receiving coil produces an alternating waveform from the magnetic field, and a rectifier rectifies the alternating waveform to deliver power having a rectified voltage. A modulation circuit causes a loading circuit to be coupled to and uncoupled from the receiving coil at a pre-determined modulation rate when, for example, the rectified voltage is greater than a threshold voltage. Back in the transmitting device, a modulation detector circuit detects modulation of the load impedance, and when the load impedance is modulating at the pre-determined modulation rate, causes the drive signal circuit to adjust a characteristic of the drive signal, resulting in an adjustment in an intensity of the magnetic field.

    Abstract: This invention encompasses embodiments for multi-modal integrated simultaneous measurement of various aspects of fluids contained in circulating systems such as automotive reciprocating engines and vehicle transmissions. These circulating systems perform constant internal lubrication, and heat and contaminant removal to protect the internal moving parts from the inherent friction and damage in normal operation. Most commonly this is achieved with fluids based on hydrocarbon and/or related synthetics, which, over time, can lose their protective properties, and vary in their performance or breakdown/decay due to internal and external events. Several components within the lubricant fluid can be measured and can provide insight into the efficacy of the system to perform its designed mission. The mass and level of the fluid may also be monitored on an on-going basis. Described herein is a real-time, simultaneous, integrated, multi-modal sensor system for early warning notification.

The charging control device includes: a charging converter which takes electric power out of a solar panel and converts the electric power to a voltage required for charging a storage battery; and a controlling CPU which adjusts an output voltage that is outputted from the charging converter. The charging converter takes electric power out of the solar panel at two operation points where the electric power can be taken out of the solar panel with a certain output voltage, and charges the storage battery. The controlling CPU adjusts the output voltage in accordance with a voltage difference between input voltages respectively corresponding to the two operation points. The present technique is applicable, for example, to the charging control device of the solar power generation system.

    Abstract: An inductive battery charger is incorporated with a power source that in one embodiment is a genset. A charging surface can be provided that in some forms is hinged, separable, or includes a pocket. In some forms resonant inductive coupling can be used to charge a battery through inductive charging. A battery can be charged within an area such as a perimeter of a military post (e.g. an observation post) using techniques described herein. A battery can also be charged remotely by inductive techniques such as through the use of a passing vehicle, etc.

    Abstract: A network of collection, charging and distribution machines collect, charge and distribute portable electrical energy storage devices (e.g., batteries, supercapacitors or ultracapacitors). To charge, the machines employ electrical current from an external source, such as the electrical grid or an electrical service of an installation location. Users may also use portable charging devices that authenticate portable electrical energy storage devices or are authenticated by portable electrical energy storage devices before the charging is allowed or enabled. This authentication may be via wired or wireless communication channels between the portable charging device and portable electrical energy storage device, such as via near field communication (NFC) channels.

    Abstract: A method and apparatus for multiplexing an electrical contact interface between two electrical devices uses a time differentiated enablement of two or more different circuit elements in a first electrical device that are accessed via the multiplexed contact by a second electrical device. A timing control circuit in the first electrical device enables and disables circuit elements in the first electrical device coupled to a shared information contact over time. The second electrical device interacts with a first circuit element during an initial period upon connection to the first electrical device, and then interacts with a second circuit element after the initial period.
