Abstract:
A tilt control method for a near-field optical disc drive is provided. A gap between a lens and a disc is estimated. A tilt compensation for the lens is estimated according to a tilt signal when the lens is within a far-field region. A coarse tilt control is performed on the lens according to the tilt compensation when the lens is within the far-field region.

A gain corresponding to the gap is provided. A tilt signal is detected. A tilt compensation value according to the tilt signal and the gain is obtained. A tilt adjustment control is performed on the lens according to the tilt compensation value.
Abstract:
A femto access point (FAP) for use in a network system and a communication method for the femto access point are provided. A mobile station is wirelessly connected to the FAP. The FAP comprises a storage unit, a sniffer unit, and a process unit. The sniffer unit sniffs a packet of the mobile station. The process unit retrieves an identity (ID) code of the mobile station from the packet and stores the ID code into the storage unit. The process unit further establishes an uplink local area network (LAN) service flow and a downlink LAN service flow of the mobile station. The uplink LAN service flow and the downlink LAN service flow established by the FAP and the mobile station are used to transfer packets within the LAN.
Abstract:
A method for calibrating an SA compensation level of an optical drive is provided. The method includes steps of providing a plurality of SA compensation levels; obtaining a peak-to-peak value of an S curve corresponding to each of the SA compensation levels; selecting a maximum of the peak-to-peak values of the S curves and the SA compensation level corresponding to the maximum; and setting the selected SA compensation level to be an optimal SA compensation level.
Abstract:
A socket connector (100) includes a base (1) defining a receiving room, an insulative housing (2) received in the receiving room, a number of contacts (6) retained in the insulative housing, a floating plate (3) secured to the base and attached to an upper face of the insulative housing, and a number of springs (7). The insulative housing includes a first block portion (22), a second block portion (21) located upon the first block portion, and a side shoulder (23). The floating plate includes a rectangular main portion (30) and a plurality of fixing legs (31) extending from corners of the main portion towards the base. The springs have a first group of springs sandwiched between the edges of the main portion and the base, and a second group of springs sandwiched between the fixing legs and the side shoulder of the insulative housing.
Abstract:
An electrical connector (100) electrically connects a first IC package (800) having a first width and a second IC package (900) having a second width different from the first width. The electrical connector includes an insulative housing (2) defining a number of contact recesses (20), a number of contacts (3) inserted in the contact recesses, a connecting member (4) mounted on the insulative housing, and a number of guiding members (6) assembled to the connecting member for guiding the first IC package in the connecting member at a first state, and detachable from the connecting member for facilitating insertion of the second IC package in the connecting member at a second state.
Abstract:
A field emission device has pixels with cathode and anode provided on the same plane, so that electrons directly penetrate an independently provided fluorescent powder layer to produce light, giving the display the advantages of easy focusing, no dark spots, high brightness, and enhanced light emitting performance. Since the light produced by the fluorescent powder layer is not blocked by the anode, the problem of charge accumulation on the fluorescent powder layer is avoided, and it is not necessary to use expensive light-transmittable conducting glass as the anode. With the cathode and the anode located at the same plane, it is not necessary to use a high precision spacer to maintain a fixed distance between the cathode and the anode, enabling the device to be manufactured at reduced cost and high good yield.
Abstract:
A socket adapted for interconnecting an IC package (3), such as TSOP (Thin Small Outline Package), and a circuit board, includes a socket body (1), a plurality of contacts (2) received in the socket body, and an operating member (5) movable mounted on the socket body. Each contact includes a base portion (21) retained into the slot of the socket body and a first and a second contact beams (24, 25), each extending upwardly from an upper edge of the base portion. When a force is applied on the operating member, both of the first and the second contact beams cooperated with the operating member and moving away from its original position. A stick (6) mounted to the member (5) may be provided to cause movement of the second contact (25).

Abstract:
A socket adapted for electrically connecting a semiconductor package to a printed circuit board, includes a main body defining a number of contact passageways and a plurality of contacts received in the contact passageways of the main body. Each contact has a base portion, a first contacting portion and a second contacting portion upwardly extending from the base portion, and a spring arm bent from a bottom edge of the base portion. The spring arm extends substantially in a horizontal direction and is bent downwardly at a free end thereof to form a tail. The spring arm can deform to provide an elastic force for the tail to press against the printed circuit board.
