Abstract: A hybrid alfalfa variety designated HybriForce®-420/Wet and deposited as ATCC Accession Number PTA-5858. Also disclosed is a hybrid alfalfa plant or part thereof derived from the seed deposited as ATCC Accession Number PTA-5858. This variety also has an increased level of tolerance to saline soils within dormant alfalfa.

Abstract: MRAM noise stabilizing and reducing apparatus and methods for MRAM sensing operations injects noise generated by activation of a word line (80, 82, 84, 86) into a sense line (128) and a reference line (130). Sense strings (20, 22, 24, 26) addressed by the word line (80, 82, 84, 86) are alternately coupled to the sense line (128) and the reference line (130). Cross coupling reduces the noise injected on the sense lines (128, 130). Cross coupling also balances the noise created by activation of the word line (80, 82, 84, 86) between the sense line (128) and reference line (130). A sense string (20, 22, 24, 26) not addressed by the word line (80, 82, 84, 86) provides a reference signal. A differential amplifier (132) includes circuitry to compare and store a difference between the sense line (128) and the reference line (130). The stored value can be further compared to a second value obtained by reversing the current on the word line (80, 82, 84, 86).

Abstract: A lighter includes a casing with liquid gas received therein and an igniting member is located in the casing for igniting the gas released from a light hole in a top of the casing. An activation piece is pivotably connected between two walls of the casing and a cap is connected to the activation piece and engaged between the two walls of the top of the casing. A stop is located at an edge of the cap and contacts an edge of the casing to prevent the cap from being pushed before it is slid to skip the stop from the edge of the casing.

Abstract: A wrench comprises a handle and a head extended from the handle. A web is defined between the handle and the head. The head includes a compartment in which a drive member is rotatably received. The web includes a transverse through-hole having an intermediate portion communicated with the compartment. A cavity is defined in the web and communicated with the transverse through-hole. A switch member is mounted in the cavity and rotatable relative to the handle between two positions corresponding to two opposite ratcheting directions of the handle. A pawl is slidably mounted in the transverse through-hole for engaging with the drive member. The pawl remains in the transverse through-hole during operation.
