摘要:
A handheld controller which includes at least two disparate sensors, such as a motion sensor and a touchpad sensor. A processor deployed in either handheld controller or separate product implements a hybrid pointing and selection method that uses data from the first sensor to adjust the sensitivity to stimulus of the second sensor, and vice versa. The respective sensor data are thus tempered and combined to generate a cursor control signal that includes a large scale control component to control size and movement of a rough pointer region, and a fine scale control component to control position of a precise pointer within the rough pointer region.

A ground-effect footplate against which a user applies plantar force and moves their foot in 3D across all seven lower-extremity biomechanical axes to accomplish specific as well as global ambulatory objectives related to lower extremity performance improvement, injury prevention and rehabilitation. A device comprising at least one articulating leg connected to a ground-effect footplate and a surface for a user to position against. The device can be used in conjunction with software to create virtual ambulatory environments that mimic GRFVs and cause moments of force that initiate muscular activations that substantially mimic human ambulation, and can couple those movements with non-functional movements in order to improve ROM, speed, strength, and proprioception.

A secure system for user authentication comprised of an authentication interface having a character dial and alignment markers is provided. A passcode input module receives user commands to move the character dial with respect to the alignment markers and to record a configuration of the characters with respect to the alignment markers, thereby creating alignment configuration data. A passcode generation module receives at least one of said alignment configuration data from passcode input module and generates a plurality of passcode hypotheses. An authentication module receives the passcode hypotheses and compares the passcode hypotheses with the passcodes of registered users stored in a data store. The passcode hypotheses are updated after each new alignment configuration data entered by the user. The authentication module authenticates a user upon finding a passcode hypothesis matching a stored passcode.

Apparatus and methods are provided for measuring a size of an object in a field of view of a captured image. A distance is measured from a focal point of the image to the object. A cursor is fit to the object and the size of the object is estimated based on processing the measured distance, image parameters and the cursor. Alternatively, a model having dimensions corresponding to the object boundaries is fit to the object boundaries. At least one dimension is estimated from among the dimensions of the fitted model. The size of the object is estimated by determining the dimensions based on the estimated dimension, image parameters and the fitted model.

A device usage monitoring and control system for accomplishing parental monitoring and control of devices connected to a home network includes a permissions module receiving and storing control commands from a parent defining permissions with respect to one or more children. The permissions specify levels of access to devices connected to a home network and/or classifications of media content consumable via the devices. A control module grants a child access to the devices and/or media content via the devices based on the levels of access. A monitoring module monitors the child's usage of the devices and/or the child's consumption of media content via the devices, stores a related usage history, and communicates the usage history to the parent.

摘要:
The invention relates to a method and device for controlling a physical parameter of an optical signal. According to the invention, a portion of the initial optical signal (SE) having passed through an optical waveguide from the input (24.1) to the output (24.2) thereof, is returned into said optical waveguide (24) using a sequential circulator (25) and an optical amplifier (28), in order to at least partially form the optical control signal (SE2), which counter-propagates relative to said initial optical signal (SE), so as to stabilize, or at the very least control, the physical parameter of said initial optical signal when the latter exits said optical waveguide (24) via the output (24.2) thereof.
