Abstract:
According to one embodiment, a semiconductor die having increased usable area has at least six sides. The semiconductor die has a reduced stress at each corner of the die, resulting in smaller keep out zones near the corners of the semiconductor die, which allow the placement of bond pads near each corner of the die. The semiconductor die further allows the placement of active circuitry near each corner of the semiconductor die. One embodiment results in a 5.0% increase in usable area on the semiconductor die.
Abstract:
According to one embodiment, a semiconductor die for increasing usable area of a wafer and for increasing yield has a substantially hexagonal shape. The wafer can have, for example, a circular shape. The semiconductor die can be diced by, for example, using a water-jet-guided laser. In one embodiment, the semiconductor die results in an approximately 2.0% to 4.0% reduction in the unusable area of the wafer. Moreover, the substantially hexagonal shape of the semiconductor die reduces stress at corners of the semiconductor die, thus increasing the yield of the wafer.
Abstract:
A test apparatus for testing a to-be-tested network connection device is disclosed. The to-be-tested network connection device has a number of to-be-tested ports. The test apparatus includes a packet generator and a switch fixture. The packet generator is for generating a test packet having a VLAN ID (VID). The switch fixture, having VLAN function, includes a number of fixture ports. The to-be-tested ports are respectively one-to-one electrically coupled to the fixture ports. The switch fixture receives the test packet and transmits the test packet from one of the fixture ports to the corresponding to-be-tested port according to its VID in order to verify the to-be-tested network connection device.

Abstract:
A method of direction finding (DF) positioning in a wireless location area network (WLAN) is proposed. A multiple antenna IEEE 802.11 transmitting device can transmit signal preamble containing multiple Long Training Field (LTF) symbols in a radio frame from multiple antennas simultaneously, which allows a receiving device to resolve multiple DF sounding signals transmitted from the multiple antennas. As a result, angle of departure (AoD) of the transmitting device can be estimated by using the multiple resolved DF sounding signals from each antenna for DF positioning purpose.
Abstract:
An electronic device includes a first body, a second body, an electrical connection element, and a hinge structure. The electrical connection element is configured to electrically connect the first body with the second body. The hinge structure is configured to pivot the first body with the second body. The hinge structure includes two mounting bases, two first linking assemblies, and a second linking assembly. Each of the mounting bases is connected to the first body and the second body. The two first linking assemblies are respectively pivoted to the two mounting bases. The second linking assembly is disposed between the two mounting bases, and two opposite terminals of the second linking assembly are movably connected to the two mounting bases respectively. The second linking assembly has a receding space configured to accommodate a portion of the electrical connection element.
Abstract:
A non-contact testing system and method using acoustic sensors and a mobile sensing system using this system and method is disclosed. The leaky surface wave is recorded with directional microphones. A fast inversion analysis algorithm is introduced to estimate the shear velocity profile and elastic modulus for the subsurface layers of pavement structures, using the dispersion curves obtained from the acoustic signals. An electrical hammer is used to produce impact impulses automatically. A mobile sensing system is integrated on a mobile cart to perform the mobile subsurface sensing for pavement structures.
