Abstract: The invention concerns the use of duplex oligonucleotides about 25 to 30 base pairs to introduce site specific genetic alterations in plant cells. The oligonucleotides can be delivered by mechanical (biolistic) systems or by electroporation of plant protoplasts. Thereafter plants having the genetic alteration can be generated form the altered cells. In specific embodiments the invention concerns the alteration in the gene that encode acid invertase, UDP-glucose pyrophosphorylase, polyphenol oxidase, O-methyl transferase, cinnamyl alcohol dehydrogenase, ACC synthase and ACC oxidase or etr-1 or homolog of etr-1, and plants having isolated point mutations in such genes.

Abstract: An elliptical exercise device includes a frame having a first pivot axis and a longitudinal axis, at least one foot link and at least one swing arm. The foot link is coupled to the frame and is constrained to move in an orbital path approximately parallel to the longitudinal axis. The swing arm is also coupled to the frame and has a reciprocating movement whereby a natural “stride” movement of the arm of a user is replicated. The swing arm operates independently from the foot link. The natural “stride” movement of the arm of the user grasping the arm link follows a generally concave motion relative to the ground. The length of the movement of the arm of the user is defined by the user. A different resistive load can be applied on the arm apparatus than on the foot links.

Abstract: An elliptical exercise device including a frame having a pivot axis, a foot link, a coupling, a swing arm, an engagement mechanism, and a guide system. The foot link has rearward, forward and foot support portions. The foot support portion has a central location. The coupling couples the rearward portion to the pivot axis so that the rearward portion of each foot link travels in a closed path relative to the pivot axis. The engagement mechanism has a first portion coupled to the swing arm and a second portion coupled to the foot link at a location rearward of the central location. The guide system supports the forward portion of the foot link along a preselected reciprocating path of travel as the rearward portion of the foot link travels along its path of travel. The guide system is selectably positionable in a plurality of different positions.

Abstract: An exercise device is provided including a foot link having a rearward end and a forward end. An adjustable stride mechanism is provided. The adjustable stride mechanism includes a primary gear and a secondary gear. The primary gear is sized larger relative to the secondary gear. A primary crank connects the primary gear and the secondary gear. A timing belt connects the primary gear to the secondary gear. The primary crank and the timing belt enable the secondary gear to rotate around the primary gear. A secondary crank is pivotally attached to the secondary gear and to a foot link. The secondary crank creates an ellipse-shaped path for the foot link as the secondary gear rotates around the primary gear. Thus, the foot link motion combines an at least a dual ellipse motion. An automatic adjusting mechanism can be provided to adjust adjust the adjustable stride mechanism.

Abstract: In an embodiment, an apparatus includes a projection subsystem to project an image-containing beam, and an image adjustment element. The image adjustment element is to cause adjustment of the image-containing beam in response to a detection of relative movement of the apparatus with respect to a reference object. A method includes determining whether substantial relative movement of a projection system has been detected, in an embodiment. When substantial relative movement has been detected, the method further includes producing control inputs, and altering operation of one or more image adjustment elements and/or altering image data in response to the control inputs, in an embodiment.

Abstract: A multichannel optical amplifier having an adjustable gain set point is controlled to permit substantially constant gain tilt control during a gain set-point change so that the channel powers are maintained during system modification. To this end the amplifier comprises an erbium doped fibre (EDF) loop and associated pump amplifier for amplifying an optical signal comprising channels of different wavelengths, a variable optical attenuator (VOA) for controlling the gain of the amplifier by applying a loss profile that varies with wavelength so that the different channels are amplified in accordance with a required gain tilt, preferably a zero gain tilt, and a PI controller for applying a gain tilt adaptation profile to compensate for an inherent gain tilt to produce the required gain tilt.

Further provided are methods for the expression of transgenes in plants comprising the use of these sequences. The methods of the invention include the direct creation of transgenic plants with the promoters by genetic transformation, as well as by plant breeding methods. The sequences of the invention represent valuable new tools for the creation of transgenic plants, preferably having one or more added beneficial characteristics.

Abstract: A reflector comprises a core and a first dielectric mirror formed over at least a portion of the core to reflect light having a preselected wavelength. The reflector may comprise a plurality of dielectric mirrors formed concentrically over the first dielectric mirror to reflect light having the preselected wavelength. The multiple dielectric mirrors may have different diffraction indices. A layer of such reflectors deposited onto the reflective surface of a projection screen may enhance the reflective selectivity of the screen to the preselected wavelength. Reflectors formed to reflect different wavelengths may be deposited onto the reflective surface to enhance selectivity to the different wavelengths and minimize reflection of ambient light.
