Abstract: The invention concerns an apparatus for scanning the optical properties of materials using a stationary sample stage and a dual-axis rotational system. The apparatus includes motors for azimuthal and polar rotation, supporting an optical system with adjustable lenses and filters to collect data from multiple angles. This design is particularly advantageous for photo-excited materials using linearly polarized sources, as it maintains static pump polarization, eliminating the need for additional motors or optical elements to align the pump with the sample's rotation. This avoids complications with halfwave plates and broadband retarders, which may not preserve linear polarization across all wavelengths. The modular system accommodates various detectors, ensuring versatility while enabling precise, high-resolution spectral imaging.

Abstract: A grill removal tool with integrated knuckle handle loop that allows for the vertical application of force for removal of a barbeque grill has a loop handle with shoulder contours that extend to for arms with hooks at each end. The loop handle joins the two arms. The hooks are at the distal end of each arm. The hooked portions are the reaction element that is used to engage the barbeque grill during removal from or manipulation over a heat source. The basic concept is that the user is able to use the grill by placing the looped portion of the hook over their knuckle with a closed grip to allow or vertical removal of a barbeque grill with or without food present on the grill. The hooks are compatible with 100 percent of consumer grills on the market since the hooks are adequately fitted between spaces in grates.

Abstract: A hand and wrist exercise device is provided that allows a user to strengthen or rehabilitate hand muscles, wrist muscles, or finger muscles. The device is preferably designed using plastic tubing so that it is light weight and easy to assemble and disassemble. A multitude of elastic members are attached to a frame structure and to finger securing devices. By inserting one's fingers into the finger securing devices, a user can perform various resistance exercises. Additionally, a pole is attached at both ends to elastic members that are secured to the structure. This allows a user to rest a forearm on a pad located on the frame structure and perform wrist curls, reverse curls, or wrist twists against resistance provided by the elastic members. To adjust the resistance levels provided by the exercising device, one only needs to change the elastic members. This makes it easy to adjust the resistance to appropriate levels for different users.

Abstract: A frame for a motorcycle comprises two or more plate-like members removably secured together in spaced relationship. The plate members are maintained in spaced apart relationship by a number of spacers and secured in place by threaded end portions that extend through apertures in the plate-like members and engage the spacers. The major components of the motorcycle, such as the engine, petrol tank and front fork, are secured between the plate members. The entire frame can be disassembled by removing the threaded end portions and spacers, and then separating the plate members.
