Machine-readable media, methods, apparatus and system are described. In some embodiments, a host platform may receive a first USB command from a client platform, wherein the first USB command notifies the host platform that a USB device is plugged into the client platform. The host platform may further create a virtual USB device as a virtualization of the USB device in response to the first USB command, and may establish a USB device driver in response to the creation of the virtual USB device. The USB device driver may control the USB device in the client platform.

The present invention provides a transition-isolating drive circuit for a synchronous rectifier. In one embodiment, the transition-isolating drive circuit includes drive switches coupled to a transformer winding and configured to provide drive signals for the synchronous rectifier. Additionally, the transition-isolating drive circuit also includes a conduction-inhibiting circuit, coupled to the drive switches, that increases a turn-off voltage of the drive signals to a predetermined level.

An improved writing instrument includes a main casing, a head portion, a relay rod, and a tail stopper. The head portion can be connected to the main casing and is centrally provided with a tip hole for passage of a reservoir tube. The tail stopper can be fitted to the relay rod. A core tube is disposed between the main casing opposite to a rear end of the head portion and the relay rod opposite to the tail stopper. The end of the core tube facing the head portion is provided with a core chamber, whereas the end facing the tail stopper is formed with a core tube hole. The section of the core tube facing the tail stopper has a smaller external diameter, with two or more ball holes symmetrically disposed therein. A core post is inserted in the core tube and has a post ring of a larger external diameter formed at a rear end thereof to serve as a limit. An intermediate portion of the core post is provided with a core groove corresponding to the positioning balls. A movable ring is slidably disposed between the relay rod and the core tube. When the head portion faces down, the core post and the movable ring slide downwardly, and the core post is restricted by the positioning balls and the movable ring. When the head portion faces up, the movable ring and the core post lower and retract.

A method and system for associating active regions with positions within displayed images in a device and display independent manner. Active regions are described by client-side image maps include in hyper-text markup language descriptions of web pages that include specifications of images to be displayed within the web pages. The specifications of images and descriptions of client-side image maps are replaced by servers with a parameterized call to an image viewer, invoked by a browser on a client computer to display the image. The browser maintains an internal description of the positions of active regions in image-relative coordinates, thereby providing dynamic viewing of web pages that include images with associated active regions while maintaining the originally-defined correspondence between the active regions and images.

A locating structure for a bounce device in a pen, having a hollow penholder, a locating device, and a center stick. The penholder has an end with a transverse guide groove and a locating hole below the guide groove. The locating hole has a size greater than the guide groove. The locating device has a slide block with a lateral locating hole, a pushbutton with a spring locating at a bottom and received in the locating hole, a slide block inserted into the penholder through the opening. The pushbutton has a stepped end shape providing a slide tenon and a stop ring corresponding to the guide groove and the locating hole respectively, and also providing a stop flange having a size greater than the locating hole. When the pushbutton is pushed to move the slide tenon downward along the guide groove, the spring urges the stop ring to fit with the locating hole. Thus, the slide block has the writing part extend outward from the penholder. When the slide tenon is pressed and the pushbutton moves inward in the locating hole, the writing part retreats in the penholder.
