摘要:
A toilet cleaning apparatus comprising a toilet brush head; a toilet brush handle (2) separated from the brush head by a brush shaft (1); a portion of the brush handle being adapted to contain a cleaning fluid and being in fluid communication with the brush head by a conduit; the handle being adapted to be reciprocally displaced along the conduit between a first position remote from the brush head and a second position proximate to the brush head so urging cleaning fluid from the handle to the brush head; and, a non return valve within the conduit adapted to allow the flow of fluid from handle to brush but to prevent the flow of fluid from brush to handle.

A method and fixture using magnetic field assisted self-alignment for chip packaging. Typical embodiments include a magnetic device having one or more pole groups, each pole group including two or three poles. Some embodiments provide multiple pole groups arranged in a one or two dimensional pole group array. The poles can build up a self-alignment magnetic field. The structure of fixture is simple and easy to implement. Typical embodiments can greatly reduce chip packaging cost and make packaging more efficient. In accordance with typical embodiments, a chip and a substrate can be self-aligned magnetically regardless of their shapes.

A high density, low voltage, and low-power one time programmable (OTP) memory is based on core cells with a one transistor design. A CLEAN pulse is directed to a single shunt device at the output of the column decoder so spurious charges that may have been stored in the floating nodes can be cleaned up. Such arrangement also allows for the simultaneous initialization of bit lines, data lines, and sensing lines to zero. Core area layout size is substantially reduced, and operational power requirements are exceeding low making these particularly suitable in HF and UHF RFID applications.

A method of providing an online verifiable consent from a parent to a minor to permit usage of an online education system and that prevents misrepresentation and unauthorized access is provided. The method comprises establishing a relationship between an adult parent and a minor and based on the relationship verifying whether the adult parent permits the minor access to the online education system. If the adult parent permits the minor access, the method then grants access to the minor to the online education system.

A system and method for providing device management and sharing in an Instant Messenger system is provided. An instant messenger server and an enhanced instant messenger module are operatively coupled together. The enhanced instant messenger module has an instant messenger process and a networked device process, the instant messenger process being operable to provide instant messaging functions and services to a user and the networked device process being operable to provide data from networked devices to the instant messenger server.
摘要:
A microporous separator film for electrochemical cells and a method of making such films is disclosed. The microporous separator film includes an intimate mixture of an electrically insulating matrix phase and a self-switching voltage activated conductive phase, wherein the voltage activated conductive phase provides a plurality of conductive paths from a first face of the microporous separator film to a second face of the microporous separator film. The method for making the composite microporous separator film includes the steps of forming an intimate mixture of at least an insulating matrix phase and a self-switching voltage activated phase, forming a film from the mixture, and generating pores within the film.
