Architecture is provided that facilitates user-controlled access to user profile information. A user is allowed to selectively expose (or mask) portions of his/her profile to third parties. Additionally, advertisers and/or content providers can offer incentives or enticement in response to the acceptance of which a user exposes larger portions of their profile. The architecture comprises a system that facilitates profile management utilizing a profile component that facilitates creation and stor...

This disclosure describes a temperature controlled photodetector. The disclosed detector can reach a temperature at which responsivity is maximized within a short time and with little wasted power. Furthermore, the photodetector prevents thermal gradients from developing across the detector so that the whole detector region has equivalent responsivity.

A numerically controlled oscillator (NCO) is arranged to accumulate control values for each transition of a system clock to provide an accumulation signal and an edge signal. A speed multiplier value (N) is selected to simulate a desired clock resolution of N times the system clock resolution. The multi-phase predictive clock circuit is arranged to provide clock phase output signals that each correspond to a predicted clock phase as if the system clock where running at N times faster than the ac...

Generating a routing system for a three-dimensional model of a real-world object includes specifying a set of connections, applying a filter to the connections to prevent more than one connection having the same first connector and the same second connector from being rendered more than once, creating geometric entities that are curves and that represent the connections, and displaying the routing system in a visually simplified manner by rendering the plurality of geometric entities. Additional...

A calibration circuit (20, 50) and method (60) for calibrating the bias current of a VCO (10, 40) to minimize phase noise. The calibration circuit (20, 50) monitors the average voltage at the common-mode node of the VCO (10, 40) while varying the bias current over a predetermined range. The calibration circuit (20, 50) identifies the bias current associated with the minimum average common-mode voltage and utilizes this bias current for calibrating the biasing transistor of the VCO (10, 40).

The invention comprises a radio controlled tree planter. The planter has four hydraulically controlled tree spades mounted on vehicle, with hydraulic cylinders to position the spades in a storage, position, a vertical digging position, and a actual digging action. A tv size radio transmitter has button controls for transmitting radio signals to a radio receiver mounted on the planter, which receiver in turn transmits signals to solenoids operating the hydraulic cylinders to thereby control the m...

A magnetic heater is provided having a conductive member and a first magnet assembly comprising a frame and at least one magnet disposed a distance adjacent the conductive member, wherein the first magnet assembly and the first frame are adapted to rotate relative to each other about an axis so as to induce eddy currents in the conductive member when relative motion is produced between the conductive member and the first magnet assembly, the at least one magnet adapted to move relative to the fr...

Serving a search result that includes an access controlled document includes obtaining a persistent access token that permits the verification of access to an access controlled document. The access controlled document is found in an index that includes an access controlled document and the persistent access token is used to verify authorization to access the access controlled document.

A voltage-controlled oscillator has an oscillation frequency controlled through a voltage applied across ends of a variable-capacitance element. The voltage-controlled oscillator has a frequency control bias circuit which applies to a first end of the variable-capacitance element a voltage for frequency control according to a control voltage, a first current source which generates a first current according to the control voltage, a second current source which generates a second current according...

The program for a numerical control device for controlling a numerically controlled lathe includes translation commands for translating the tool and the machining mode switching commands for switching between the normal mode by which only the tool is translated and the Swiss mode by which both the tool and the work are translated. A machining program analyzer unit analyses the program commands into translation commands and the machining mode switching commands. In response to the machining mode ...
