Title: Optical fiber bragg grating polarizer
Inventor: TRUJILLO PEDRO IGNACIO TORRES
IPC: G02B6/10
Filed: 2002-05-06

Abstract: Method and apparatus for polarizing light propagating in an optical fiber. The apparatus has an optical fiber having a Fiber Bragg Grating (FBG) section of predetermined length therein, and a force applying device for applying a lateral force to a predetermined portion of the FBG section. The predetermined portion comprises a predetermined percentage of the predetermined length. When the predetermined percentage is equal to or greater than about 10 percent, two polarization states for the light passing through the optical fiber are obtained. When the predetermined percentage is a small portion of the grating length, for example, about 1 percent of the length of a chirped grating, a finely tunable optical fiber polarizer is provided. The apparatus can use standard optical fiber such as telecomm fiber and provides various advantages including the capability of being switched on and off by simply applying and withdrawing the lateral force.

Abstract: Disclosed is a rolling cone cutter and drill bit employing multiple inserts retained as a cluster in an aperture in the cone cutter. Apertures in which the insert clusters are retained are multilobed apertures formed by intersecting bores formed in the cone steel. The apertures may also be created by forming spaced apart bores and milling regions of the cone steel that extends between the bores. The inserts in a cluster may be retained within the aperture to differing depths, may extend above the cone steel to differing extension lengths, and may have cutting portions having a variety of shapes. The inserts in a cluster may be made of different materials in order to optimize cutting duty. The bores forming the multilobed aperture may be parallel or skewed, and may create an aperture having a multilevel bottom surface so as to permit the insertion of an insert having a relatively large cutting surface in instances when the cone design would not otherwise permit the use of a cylindrical insert of the desired diameter.

Abstract: A universal kinetic diverting spout post assembly for mounting in a vertical orientation in a roman tub or deck installation is provided. The assembly includes a valve body containing a replaceable diverting cartridge into which hot and cold water are fed. The cartridge also includes a spring biased plunger assembly normally closing the outlet to a second use, such as a spray, when water normally passes through the spout to a tub and until such time as a diverting mechanism, either in response to a predetermined pressure rise in the spout when water exiting the spout is prevented, or as a direct result of the user lifting the plunger assembly. In either alternative the plunger assembly rises off it's seat and as a result closes the water path to the spout and at the same time opens the normally closed outlet to the spray and allows water to pass to the outlet. The assembly also includes a flow regulator proximate the spray outlet to prevent overpressure in a supply hose and excessive water flow therein.

Abstract: Channel Equalization of a digital TV is disclosed. In channel equalization for restoring an original signal from a digital TV reception signal having passed through a channel, the present invention includes estimating an impulse response of the channel from a received signal having passed through the channel using conjugate-gradient algorithm, finding an equalizer coefficient in a frequency domain using the estimated impulse response of the channel, outputting a signal equalized by multiplying a signal resulting from transforming the received signal into the frequency domain by the found equalizer coefficient, and predicting to remove an amplified noise of the equalized signal using the conjugate-gradient algorithm in a time domain. Accordingly, the variation of the channel impulse response according to time can be tracked in the dynamic channel having fast channel variation as well as the static channel, whereby equalizing performance can be enhanced.
