Abstract:
A passive exercise therapy station moves a patient's limb or body part through a prescribed range of motion without stress to the patient's limb or associated joints. A frame is formed of a pair of arches joined in parallel to one another, with a pair of overhead horizontal rails. One or more main cables extend over guide pulleys on the frame and past an adjustable guide carriage that travels along the overhead rails. An actuator positions the guide carriage at a desired location on the overhead rails. An exercise cable descends from the guide carriage to the patient. The exercise cable may be a web attached to the main cable. The exercise therapy station may be wheeled between rooms for therapy of a given patient.
Abstract:
Fitting a sound processing device for an individual is automated using a computer. Fitting and customisation is carried out using natural sounds without specialised audiometric equipment or audiological expertise. Software for this purpose is downloaded from an internet portal. The computer plays back acoustic signals, and obtains user input reflecting the user's perceptions of the acoustic signals, from which a hearing map is derived, representing the user's hearing. An algorithm updates the device fitting based on the hearing map. Also provided is pre-sale virtual device fitting, whereby a virtual signal processing path is established in the computer, reflecting a signal processing function of a sound processing device of interest to the user. An algorithm updates parameters of the virtual processing path, based on the hearing map. Audio signals passed through the virtual processing path are played back to the user, giving the user an acoustic indication of future device performance.
Abstract:
A universal serial bus controller pre-generates and stores a subset of USB commands in a memory, the pre-generated commands available for transmission to at least one USB peripheral device over universal serial bus, and transfers at least one command from the subset of pre-generated commands stored in the memory to the USB peripheral device over the universal serial bus. The universal serial bus controller may receive a response to the transferred command from the USB peripheral device over the universal serial bus, and send an acknowledgment packet to the USB peripheral device over the universal serial bus responsive to receiving the response from the USB peripheral device.

Abstract:
A method of controlling target aquatic microorganism pest populations by exposing the target population to an effective amount of an aquacidal compound. The aquacidal compounds are selected from the group consisting of quinones, anthraquinones, naphthalenediones, quinine, warfarin, coumarins, amphotalide, cyclohexadiene-1,4-dione, phenidione, pirdone, sodium rhodizonate, apirulosin and thymoquinone. The method is particularly effective for treating ballast water of ships or other enclosed volumes of water subject to transport between or among geographic areas to control the relocation of plants, toxic bacteria, and animals contained in the water.
Abstract:
The present invention includes systems and methods for customization of internet applications. Multiple levels of customization are applied to both static and functional aspects of user interface elements including, for example, tab-order, tab-over, immediate access keys, and hotkeys. Customization is also achieved with respect to searching over multiple user interfaces, presentation of information on a user interface, and the interaction model used by the internet application. Customization is enabled on any client supporting standard browser functionality.
Abstract:
Method and apparatus for enabling authentication of e-mail messages. A message code is embedded in an e-mail, where the message code can be used by the recipient to verify the authenticity of the e-mail. In some embodiments, this code can be created for a particular e-mail message; in other embodiments, the code is created as a watermark for use in all e-mail to a specific recipient. The message code is associated with both the e-mail message and the recipient. In the case of a message-specific code, a recipient can verify the e-mail message by inputting the code via a Web server to be looked up in the database. The invention can be implemented in a system including a server which creates e-mail messages and injects message codes and a database for storing codes and recipient e-mail addresses.
Abstract:
Embodiments of the invention relate to a method and apparatus to reduce power consumption in a passive matrix LCD driver circuit by using a plurality of drive buffers and active power management of sub-blocks in the passive matrix LCD drive circuit. Each drive buffer may operate in a first phase, which may include a high-drive mode to drive an LCD voltage to a threshold voltage level and a low-drive mode to modify the LCD voltage to approximate an input voltage of the drive buffer, and to maintain a constant LCD voltage level. The low-drive buffer consumes less current than the high-drive buffer, thus reducing power consumption. The drive buffer may also operate in a second phase, also a no-drive mode, in which the drive buffer and the bias voltage generator may be completely turned off, to further reduce power consumption. The drive buffer may be used to drive capacitive loads, as well as partially-resistive loads and inductive loads.
Abstract:
Embodiments of the invention relate to a method and apparatus to drive non-resistive loads. The non-resistive load driver may include two or more drivers, such as a high-drive circuit and a low-drive circuit, to drive rail-to-rail output voltages and to stabilize the output voltages at a substantially constant level. The high-drive circuit may drive the output voltage of the non-resistive load driver to a threshold level, whereas the low-drive circuit may modify the output voltage of the non-resistive load driver to approximate an input voltage of the non-resistive load driver, and compensate any leakage associated with the non-resistive loads to provide a substantially constant output voltage. The low-drive circuit consumes less current than the high-drive circuit. The non-resistive load driver consumes less power and use less chip space. Alternatively, the non-resistive load driver may be implemented using a single driver with multiple modes, such as a low-drive mode and a high-drive mode, by changing a bias current of the non-resistive load driver between a high current mode and a low current mode.
