摘要:
A USB 3.0 host with low power consumption includes a super speed circuit, a non-super speed circuit, and a control module. The super speed circuit is used for transmitting data at a first transmission speed. A default state of the super speed circuit is turning-off. The non-super speed circuit is used for transmitting data at a second transmission speed, a third transmission speed, or a fourth transmission speed. The first transmission speed is faster than the second transmission speed, the third transmission speed, and the fourth transmission speed. The control module is used for detecting whether a USB peripheral device is connected to the USB 3.0 host, and controlling turning-on and turning-off of the super speed circuit.

The invention provides an optical measurement device for measuring light to be inspected. The optical measurement device comprises a light receiving module, a light splitting module, and a plurality of color filters. The light receiving module is used for converting the light to be inspected into a first parallel light. The light splitting module is used for splitting the first parallel light into a plurality of parallel lights to be inspected. Each color filter receives at least one of the plurality of parallel lights to be inspected. The plurality of parallel lights to be inspected filtered by the plurality of color filters are used to calculate tristimulus values in the CIE color space.

A flexible circuit with multiple independent mounting points can be mounted (soldered) to substrates by independently (and concurrently) positioning mounting points in x, y, and theta (angular rotation) with vacuum chucks. In one embodiment the vacuum chucks can be guided by computer aided vision to locate and match fiducials on the flex circuit with fiducials on the substrate. In one embodiment, hot bars can be used in a subsequent bonding operation to secure an adhesive coupling between the flexible circuits and the substrate.

A conductive strap device for establishing dual electrical paths with a person's body includes a coaxial fastener structure having a spring-loaded contact pin to provide a first electrical path and a conductive member arranged coaxially with and electrically insulated from the contact pin to provide a second electrical path.
摘要:
A static electricity grounding strap for connecting a person to electrical ground comprising a clasp body having two clasping means to fasten a strap belt of conductive materials. In one embodiment of the present invention, the clasping means is made of non-conductive material. The electrical connection path is conducted via a single conductive plate from the strap belt, a fitting means and a grounding cord to ground. The conductive plate can also be divided into two conductive section separated by a non-conductive partition to provide a dual-loop grounding paths. In another embodiment, the clasping means is made of conductive materials and no additional conductive plates are needed.
