An implantable medical device, such as a bi-directional infuser device for hydraulically controlling an artificial sphincter (e.g., adjustable gastric band) benefits from being remotely powered by transcutaneous energy transfer (TET), obviating the need for batteries. In order for active components in the medical device to operate, a sinusoidal power signal received by a secondary coil is rectified and filtered. An amount of power transferred is modulated. In one version, a voltage comparison is made of a resulting power supply voltage as referenced to a threshold to control pulse width modulation (PWM) of the received sinusoidal power signal, achieving voltage regulation. Versions incorporate detuning or uncoupling of the secondary coil to achieve PWM control without causing excessive heating of the medical device.

The sensors can be of various configurations and types, for example: optical, chemical, temperature, pressure or other sensors including effectors for applying signals to surrounding tissues. The sensors / effectors are arranged on a flexible and stretchable substrate with incorporated active components that allow the effective size, configuration, number and pattern of sensors / effectors to be dynamically changed, as needed, through a wired or wireless means of communication. Active processing allows many channels to be combined either through analog or digital means such that the number of wires exiting the array can be substantially reduced compared to the number of sensors / effectors on the array.

As computer programs grow more complex, extensible, and connected, it becomes increasingly difficult for users to understand what has changed on their machines and what impact those changes have. An embodiment of the invention is described via a software tool, called AskStrider, that answers those questions by correlating volatile process information with persistent-state context information and change history. AskStrider scans a system for active components, matches them against a change log to identify recently updated and hence more interesting state, and searches for context information to help users understand the changes. Several real-world cases are provided to demonstrate the effectiveness of using AskStrider to quickly identify the presence of unwanted software, to determine if a software patch is potentially breaking an application, and to detect lingering components left over from an unclean uninstallation.

A passive harmonic switch mixer is shown that is immune to self mixing of the local oscillator greatly reducing leakage noise, pulling noise, and flicker noise when used in a direct conversion receiver or direct conversion transmitter circuit. The passive harmonic switch mixermixes an input signal received on an input port with an in-phase oscillator signal and a quadrature-phase oscillator signal and outputs an output signal on an output port. Because the quadrature-phase oscillator signal is the in-phase oscillator signal phase shifted by 90 °, the passive harmonic switch mixer operates with a local oscillator running at half the frequency of the carrier frequency of an RF signal. Additionally, because the passive harmonic switch mixer has no active components, the DC current passing through each switch device is reduced and the associated flicker noise of the mixer is also greatly reduced.
