Title: An optical fiber/waveguide polarizer and a method of fabrication
Inventor: HILL KENNETH O
IPC: G02B5/30
Filed: 2005-09-26
Granted: 2012-03-13
Abstract: The invention relates to an optical fiber polarizer comprising an optical fiber with at least a core, a cladding and surrounding medium (or outer cladding) where one or more sections of the optical fiber include periodic/aperiodic (chirped, quasi-periodic) modulation of the dielectric properties of the fiber in the direction of propagation of the light (the longitudinal axis of the fiber). The modulation of the dielectric properties of the fiber is such that it introduces periodic/aperiodic birefringence a long the direction of propagation of the light, such a modulation usually but not necessarily being confined to the vicinity of the core region of the fiber. Means are included to attenuate preferentially some of the modes of propagation of the fiber, specifically modes of one principal state of polarization and not the orthogonal state of polarization.

Abstract: A controller compares a minimum value of power source voltage which decreases in association with starting current generated upon start of a motor with a threshold value in a storing unit. When the minimum value is less than the threshold value, the controller notifies of shortage of the power source terminal voltage, and stops the motor. The controller also compares a value obtained by integrating the power source voltage which decreases in association with starting current generated upon start of the motor for only predetermined time with the threshold value in the storing unit, when the integral value is less than the threshold value, notifies of shortage of the power source terminal voltage, and stops the motor.

Granted: 2016-01-05
Abstract: The invention relates to improved methods of amplifying and quantifying a plurality of selected nucleic acid molecules from a pool of nucleic acid molecules. A first round of multiplex amplification used where the amplification reaction is allowed to proceed to a point prior to that at which significant competition between amplicons for reaction components has occurred. This is the followed by a second round of amplification that typically includes a fluorescent reporter to allow for each of the selected nucleic acid sequences to be quantified. The methods are useful for the amplification and quantification of nucleic acids from a variety of sources, such as gene expression products, whereby many such products may be amplified and quantified from very limited samples and from degraded archival samples.

Granted: 2011-10-18
Abstract: A collapsible window covering capable of height adjustment, comprising, in combination, an upper elongated support, a lower elongated member that is adjustable up and down, and control lines extending downwardly to suspend said lower elongated member. A primary rotor structure at the upper elongated support entrains the lines. Dual rotary members act on the lines to exert a counterbalancing suspension force on the lines at different window covering height adjusted levels. One dual rotary member exerts tensioning force on the lines and there is an S-shaped spring coupled to the dual rotary member acting to urge the one rotary members in a direction for winding the lines on the one rotary member. The upper elongated support includes a straight channel with a receptacle in the channel in which the dual rotary members and the spring are protectively carried. The channel orients the receptacle so that the lines in the channel remain substantially aligned with the one rotary member in the receptacle.

Title: Techniques for handling inconsistencies in enqueue lock information
Inventor: CHAN WILSON WAI SHUN
IPC: G06F9/52
Filed: 2006-06-09
Granted: 2011-07-26
Abstract: Techniques are described herein for handling lock- related inconsistencies. As mentioned above, such inconsistencies occur when two or more sets of lock information, relating to the same resource, convey inconsistent information about locks requested and/or granted on that resource. In general, the techniques involve causing the locally-stored lock information about a resource to be sent to the master node of the resource . The master node of the resource compares the lock information thus received against the lock information maintained by the master node. Based on the comparison, the master node determines how to resolve the lock-related inconsistency, and sends messages to those nodes that need to change their local lock information for the resource. Once all of the lock information has been made consistent, the resource made available for access. Because the lock- related inconsistency is resolved without restarting nodes, the availability of the resources is improved .

Abstract: A ductless HVAC system is controlled by light frequency signals, for example, in the infrared (IR) band. A repeater within the line-of-sight of the ductless HVAC system is used in concert with a remote thermostat. A user may operate the remote thermostat as desired, and the remote thermostat generates and broadcasts an RF signal stream responsive to the user-entry. This suitably encoded RF signal stream penetrates any wall or other opaque impediment to light frequency transmission and is received by the repeater, decoded by the repeater, re-encoded by the repeater into a signal suitable for driving an IR transmitter and broadcast as an IR beam to the receiver/interface.

Title: Brake system for a well service or drilling hoist
Inventor: NEWMAN FREDERIC M
IPC: B01F23/47
Filed: 2006-09-08
Granted: 2012-05-15
Abstract: The brake system includes a brake lever independent of, but capable of rotating about the same point as a bell crank. Upon receiving a downward force, a member extending from the lever strikes a portion of the bell crank and generates a force that cause the bell crank to rotate. Rotational action of the bell crank transfers rotational energy to an equalizer bar thorough a linkage system. The equalizer bar's rotation increases or decreases tension on brake bands that slow a tubing drum. A cylinder can activate and cause the equalizer bar to rotate, applying tension to the brake bands and slowing the drum. Rotational energy is transferred back to the bell crank through the linkage. The rotational energy is absorbed by a spring positioned between the bell crank and the brake lever, thereby reducing the amount of sudden force passed through the brake lever to an operator.
