Abstract: A system for monitoring and regulating computer usage on a local network is disclosed. Computers on a network are configured with a client activity monitoring module that collects activity information including screen captures, keyboard activity, and/or information relating to network communications and sends the collected activity information to a network activity monitor for storage and later retrieval. Each computer on the local network periodically verifies that its client activity monitor module is operable. If a computer fails to send such verification, the system restricts network access by that computer, thus enforcing compliance with the activity monitoring system. The system further provides means for automatically displaying the collected activity information, including through screen savers, automatically changing desktop background images, and pop-up or sidebar windows.

Abstract: An on-chip capacitive device comprises a semiconductor substrate, a MOS capacitor formed on the semiconductor substrate, and a metal interconnect capacitor formed at least in part in a region above the MOS capacitor. The MOS capacitor and the metal interconnect capacitor are connected in parallel to form a single capacitive device. The capacitance densities of the MOS capacitor and the metal interconnect capacitor are, thereby, combined. Advantageously, significant capacitance density gains can be achieved without additional processing steps.

Abstract: Various systems and methods for clock generation are disclosed herein. As just one example, a system for clock generation is disclosed that includes a phase/frequency control circuit that provides a feedback control; a multi-range selector circuit that receives the feedback control; and a controlled oscillator that provides an output with a phase and frequency at least in part governed by the multi-range selector circuit and the feedback control. In various instances of the aforementioned embodiments, the controlled oscillator is a ring oscillator relying on inherent capacitance.

Abstract: A programmable current source is provided for an H-switch to dampen overshoot resulting from a drop in voltage at a node during data transitions. The programmable current source is connected to both nodes of the H-switch on each side of the write head and is responsive to a voltage drop to below a threshold voltage at one node to injecting current into the one node during the period that the node voltage is below the threshold voltage. Preferably, a second programmable current source is connected to both nodes and is responsive to a voltage rise to above a second threshold voltage at the one of the nodes to sink current from the node to dampen undershoot.
