  • Patent number: 7495410
    Abstract: Systems and methods are described for controlling power factor in motor drives having a switching rectifier providing a DC link current to an inverter in which the rectifier gain is increased to provide additional DC link current to correct the drive power factor based on current drawn by capacitors of the AC drive power input, and the inverter gain is decreased by introducing bypass states in the inverter switching control scheme or by reducing the motor flux to accommodate the increased DC link current.

  • Patent number: 7435663
    Abstract: Simple but practical methods to dice a CMOS-MEMS multi-project wafer are proposed. On this wafer, micromachined microstructures have been fabricated and released. In a method, a photoresist is spun on the full wafer surface, and this photoresist is thick enough to cover all cavities and structures on the wafer, such that the photoresist will protect the released structures free from the chipping, vibrations, and damages in the diamond blade dicing process. In another method, a laser dicing system is utilized to scribe the multi-project wafer placed on a platform, and by precisely controlling the platform moving-track, the dicing path can be programmed to any required shape and region, even it is not straight. In addition, the wafer backside is mounted on a blue-tape at the beginning to enhance the process reliability.

  • Patent number: 7435110
    Abstract: An electrical connector (100) has a first end for fitting with another connector and a second end for connecting to a board. The connector comprises an insulative housing (1), a number of contacts (2) and a metal shield (3) enclosing the insulative housing. The insulative housing includes a tongue plate (11) with a number of passageways (110) defined therein for receiving the contacts. The contacts are arranged side by side in the first end and arranged in three parallel rows in the second end. The contacts include signal contact pairs (21) and grounding contacts (22) disposed adjacent to and separating the signal contact pairs. Each signal contact pair includes a first signal contact and a second signal contact being substantially in equal length of the first signal contact. The signal contact pairs have matched impedance for transmitting high-speed signals, thereby canceling any cross talk therebetween.
