Representing HTML documents audibly includes the steps of assigning (214) unique sounds to HTML tags and events encountered in an HTML document, producing the associated sounds whenever those tags or events are encountered (218), and representing encountered text as speech (220). Speech and non-speech sounds may be produced simultaneously or substantially simultaneously. A corresponding system (10) is also disclosed.

A power supply for plural loads coupled in parallel comprises a voltage regulator, a plurality of current regulators, and an error control circuit. The voltage regulator provides a common output voltage to the plural loads. The voltage regulator comprises a sensor circuit providing a voltage sense signal corresponding to the output voltage, which provides feedback to regulate the output voltage at a selected level. The plurality of current regulators are coupled to respective ones of the plural loads. Each of the plurality of current regulators regulates current drawn by respective ones of the plural loads to within a desired regulation range. The plurality of current regulators each further provide a respective error signal corresponding to an ability to remain within the desired regulation range. The error control circuit is operatively coupled to the voltage regulator and to the plurality of current regulators. The error control circuit receives the error signals from the plurality of current regulators and provides a common error signal to the voltage regulator. The voltage regulator thereby changes the selected level of the output voltage in response to the common error signal. Accordingly, the selected level of the output voltage remains at a minimum voltage necessary to keep the plural loads in the desired regulation range.

A primary power supply and a secondary power supply are operable to supply power to at least one electrical device. A power demand of the electrical device is determined, and an efficient operating point for the primary power supply is determined. One or more of the primary power supply and the secondary power supply are used to supply power to the electrical device based on whether the primary power supply operating at an efficient operating point is operable to meet the power demand of the at least one electrical device.

Thrombus removal apparatus includes a balloon catheter with a short balloon at a distal end thereof. An aspiration catheter is disposed coaxially over the balloon catheter. The balloon catheter includes a plurality of holes for the administration of lytic agent. The apparatus does not seal off completely the zone of the vessel around the thrombus, thereby allowing movement of blood within the vessel. The balloon is shaped so that it can be pulled along the vessel in an upstream direction so as to drag against the vessel walls for assisting in the removal of the thrombus.

A color-changing emulsion for use in a freeze indicator can employ a dispersion medium, for example, an aqueous liquid, a first reactant phase and a second reactant phase, which two reactant phases can both be dispersed in the dispersion medium. The first reactant phase includes a hydrophobic liquid and a first reactant, for example, a color precursor such as a leuco dye. The second reactant phase can include a hydrophobic liquid, and includes, or can be, a second reactant, for example, a color developer such as a leuco dye developer. The first and second reactant phases can be essentially unmixed, and can be co-reactable to provide a color change. In response to a freezing temperature, the color-changing emulsion can coagulate and change color irreversibly. An intense color change can be obtained by using, for example, a suitable leuco dye precursor and developer.

A chair includes a control housing, a seat and a back support including an upwardly extending upright portion and a link portion extending forwardly from a lower portion of the upright portion. The link portion is pivotally connected to the control housing about a first pivot axis. The seat is connected to the link portion and is pivotable relative thereto. A linkage is coupled to the seat and is pivotally connected to the control housing at a second pivot axis positioned rearwardly and downwardly from the first pivot axis.

A system and method for populating an access point database includes a network of access points that are implemented to transmit access point signals by utilizing a wireless broadcasting procedure. One or more mobile devices are then configured to wirelessly receive and analyze the access point signals to produce access point scan data corresponding to the access points. A location server receives and analyzes the access point scan data to determine specific access point locations for the access points. The location server then utilizes the access point locations to populate the access point database.

A vehicle information collection system is disclosed for receiving vehicle information by way of a communication network and storing the vehicle information. The vehicle information collection system comprises: a vehicle information collection device for collecting the vehicle information of a plurality of vehicles from each vehicle by way of the communication network; and a point-issuing device that is connected to the vehicle information collection device by way of the communication network for conferring points to the vehicles according to the vehicle information. The vehicle information management unit collects and stores vehicle information at any time, and when a prescribed condition has been met, transmits vehicle information that has been stored and information indicating its own vehicle to the vehicle information collection device by way of the on-board communication unit and the network. The vehicle information collection device, upon receiving vehicle information from a vehicle, both classifies and stores the received information and transmits the information that indicates the vehicle and the vehicle information that has been received from the vehicle to a point-issuing device by way of the network. The point-issuing device, upon receiving these items of information, issues points in a number that corresponds to the amount and / or the category and / or the value of vehicle information and transmits to the vehicle information that indicates the number of issued points.
