Abstract: A turning grating coupler device comprises a waveguide core layer including a grating structure and an output slab adjoined with the grating structure. The grating structure comprises an array of sub-waveguides substantially parallel to each other along a first propagation direction. Each of the sub-waveguides has opposing sidewalls, and a width of each sub-waveguide is defined by a distance between the sidewalls. The width of each sub-waveguide is varied such that each of the sidewalls has a periodic structure that produces a sidewall periodic modulation that is out of phase with respective sidewall periodic modulations of adjacent neighboring sub-waveguides. An input edge is configured to receive a light beam from a source and direct the beam into the array of sub-waveguides in the first propagation direction. The sub-waveguides are configured to diffract the beam into the output slab in a second propagation direction substantially perpendicular to the first propagation direction.

Abstract: Methods and apparatuses are provided for evaluating or testing stiction in Microelectromechanical Systems (MEMS) devices utilizing a mechanized shock pulse generation approach. In one embodiment, the method includes the step or process of loading a MEMS device, such as a multi-axis MEMS accelerometer, into a socket provided on a Device-Under-Test (DUT) board. After loading the MEMS device into the socket, a series of controlled shock pulses is generated and transmitted through the MEMS device utilizing a mechanized test apparatus. The mechanized test apparatus may, for example, repeatedly move the DUT board over a predefined motion path to generate the controlled shock pulses. In certain cases, transverse vibrations may also be directed through the tested MEMS device in conjunction with the shock pulses. An output of the MEMS device is then monitored to determine whether stiction of the MEMS device occurs during each of the series of controlled shock pulses.

Abstract: An absorbent article is disclosed having an absorbent with first and second longitudinal sides. A liquid permeable wrapper encloses the absorbent. The wrapper extending laterally outward from each of the first and second longitudinal sides a distance of at least about 10 millimeters to form a pair of fringes. The pair of fringes are capable of being biased upward to form a pair of upstanding side walls when the absorbent article is placed in an undergarment. The upstanding side walls form a pair of reservoirs located adjacent to the absorbent. The reservoirs are capable of retaining body fluid that has run off of the wrapper until the body fluid can be absorbed by the absorbent.

Abstract: An absorbent article is disclosed having a liquid permeable bodyside cover, a liquid permeable garment side liner and an absorbent core enclosed by the cover and the liner. The absorbent article also has a pair of fringes formed by joining the cover to the liner. The pair of fringes extend laterally outward from the absorbent core and are capable of being biased upward to form a pair of upstanding side walls when placed in an undergarment. The pair of upstanding side walls form a pair of reservoirs located adjacent to the absorbent core. The pair of reservoirs are capable of retaining body fluid that has run off of the cover until the body fluid can be absorbed by the absorbent core.
