Abstract: A charger device for wireless hand-held controller is disclosed. The device comprises a DC charge socket, a contact coupled to a terminal of a rechargeable cell in a battery compartment, a charge IC electrically interconnected the DC charge socket and the contact, and an adapter for DC charging. In charging, insert the first and the second DC plugs in the DC charge jack and the DC charge socket respectively so that a required DC is automatically fetched by the charge IC from the control assembly to the cell via the contact. The invention can eliminate conventional charger seat and adapter, charge the controller without coupling to a USB port of computer and a charger jack of automobile, maintain a normal wireless signal transmission of the controller during charging, and maintain a good wireless signal transmission quality during charging by the provision of the charge IC.

Abstract: A parallelepiped portable power supply comprises a CD-ROM drive, a plurality of drawers, a top fastening mechanism for fastening a video game machine, and a power supply section including a replaceable rechargeable battery for supplying power to the video game machine in outdoors or an environment without power supply.

Abstract: A portable power supply for a video game machine such as Sony PS I mounted thereon is provided. The power supply comprises a charger, a replaceable rechargeable battery fastened in and electrically couple to the charger, and a soft protective cover shaped to conform to and secure to the received charger. The invention has further advantages of securing and protecting components and prolonging a playing time of the video game machine in an outdoor place.

Abstract: The invention is a mini pen-like wireless optical sliding-mouse with inner rechargeable battery (or discarding). It is unnecessary for usual battery exchanging. It is a portable sliding-mouse without external electric cable. It is very convenient for using and carrying.

Abstract: This invention is a “mobile phone's wireless hand-free handset built in the battery packet” and can particularly resolve the harassing problem found in the wired send/receive signal box of a cell phone; it is to insert a low power radio frequency send/receive module into the battery packet of a cell phone and the power of the battery packet is to supply the voltage required for the work; and through the connection port of the battery packet and the cell phone, a voice signal is inserted; and the regulation of the input/output of the voice signal is made in the radio frequency send/receive module and then the signal is sent into the air at an extreme low power; and at the same time, another radio frequency send/receive module is installed in a wireless headset to construct a signal communication network with the low power radio frequency send/receive module in the previous battery packet so that a simple and easy operation of a wireless hand-free handset of a mobile phone is completed.

Abstract: This creation is a “contactless charging device” with regard to a new contactless type and is applicable to the chargers for packaging and rechargeable batteries. The charger in itself is equipped with an ultrasound waves oscillator, in which the circuits is made output to an emission resonator to produce a powerful magnetic field and to radiate to the surrounding area of the charger. Moreover, within the battery packet charged is installed a receiving oscillator. The two sets of the oscillators resonate and induce the powerful magnetic field in the surrounding area of the charger and then a conversion is made into voltage and current, which are directly charged into the battery body in the battery packet. In this way, a charging effect is completed.

Abstract: This invention is a kind of “HANDHELD JOYSTICK TYPE OR MONITOR DEVICE ON THE WHEEL”, in particular, means by using the LCD monitor installed and fixed on the handheld joystick or the wheel of the video game, so the player can just carry the main body and software of the video game to play anytime and anyplace, while he won't have to sit in front of TV screen to play with video game, this will increase its convenience and entertainment.
