  • Suction device used in aging process of a microwave tube
    Patent number: 6607417
    Abstract: A suction device used in aging process of a microwave tube includes an ion pump and a suction unit respectively connected to an electron gun and a collector located in two opposite ends of the microwave tube. The suction unit includes a barrel communicated with the microwave tube and a getter disposed in the barrel. An electric power source is electrically connected to the getter. Before operation, the microwave tube along with the suction device undergo exhaust process on a heating exhaust station. After that, the electric power source supplies an electric current to electrify and heat the getter to its activation condition. Therefore, the suction device can greatly save the vacuum suction time of the aging process and the cost associated with the production of the microwave tube.

  • Temple plate pad adapted to securely engage with a temple plate of a pair of eyeglasses
    Patent number: 6565208
    Abstract: A temple plate pad adapted to a temple plate of a pair of eye glasses has a bottom plate and a tapered body securely engaged with the bottom plate and adapted to securely engage with the temple plate. The bottom plate has a width larger than a width of the tapered body so that after the tapered body is attached to the bottom plate, an inverted T shape is formed. Whereby the T shaped temple plate pad is able to receive loading due to the width of the bottom plate being larger than the width of the tapered body.

  • Enhanced delivery of audio data for portable playback
    Patent number: 6549942
    Abstract: A system for selection by a user and delivery to the user over an internetwork transmission channel of selected audio data files at a delivery rate of at least twice the delivery rate for normal, audibly perceptible playback of an audio data file. The user registers the user's selection of audio material with a central library of audio and/or text data files, and a digitized and optionally compressed omnibus file containing the user's selections is prepared and transmitted to the user at a high data transfer rate. The user receives downloads the selected data files to a personal computer or to a portable storage and playback unit (SPU) that may store and play back digitized text or audio data, using a docking station. The user carries this SPU until the user has an opportunity to audio process and play back the text or audio data files in audibly perceptible form.

  • Wrist-worn personal flash disk
    Patent number: 6536941
    Abstract: A personal flash disk for wrist wearing is disclosed. The main body has double enclosed space for setting a flash memory module and an accessory. Two interlocking straps extend in opposing directions from the main body, wherein multiple punched holes are defined through the first strap, while a buckle is fixed on the second strap. A strap carrier is attached on the second strap that can be adjusted to suitable position to accommodate the connector at one end of the first strap when the personal disk is worn on the wrist but not in use. When the personal disk is to be used, the connector is taken out and plugged into a host computer to make the connection. By incorporating a timepiece or ornamental piece, the personal disk provides a multi-function product with additional values.

  • Power supply device having two AC power inputs
    Patent number: 6535405
    Abstract: A power supply device having two AC power inputs includes a power unit that has first and second AC power inputs and a power output, a step-down and filter unit, a power regulator unit, and a detecting and switching unit. The step-down and filter unit converts the AC from the power unit to a low-voltage DC power. The power regulator unit maintains the low-voltage DC power as a stable power. The detecting and switching unit detects whether a power failure occurs on the first AC power input and subsequently switches the power supply to the second AC power input to keep a stable power supply so as to avoid any damage caused from the failure of the power supply.
