Abstract: Single-sided MRI scanners, systems, and methods are disclosed. A method can include applying a first sweeping frequency pulse defining an X axis; applying a second sweeping frequency pulse defining a Y axis; applying a third sweeping frequency pulse defining the Y axis; and applying a fourth sweeping frequency pulse defines a —X axis. The sweep rate of the fourth sweeping frequency pulse can be less than the sweep rate of the third and/or second sweeping frequency pulse. The sweeping frequency pulses can be chirp pulses. Frequency sweep DEFT pulse sequences can provide the benefits of a broader bandwidth and less sensitivity to the inhomogeneity of a single-sided MRI scanner.

The handle has first and second handle sections that are removably connected together. The first handle section includes a first receptacle and a first projection spaced from the first receptacle while the second handle section includes a second receptacle and a second projection spaced from the second receptacle. The first receptacle is adapted to receive the second projection and the second receptacle is adapted to receive the first projection when the first and second handle sections are connected together.

Abstract: A toilet seat elevator assembly includes a mounting bracket for connection to a toilet bowl and a seat elevator removably connected to the mounting bracket. The seat elevator has a generally ring-shaped portion for resting on the toilet bowl and a mounting portion with opposing mounting projections. The mounting bracket has a pair of opposing side panels and an elongate slot formed in each side panel. Each elongate slot is adapted for slidably and rotatably receiving the mounting projections of the mounting portion, so that the seat elevator may be slidably and rotatably mounted to the bracket to facilitate installation, adjustment and removal of the seat elevator with respect to the toilet bowl.

Abstract: A container rack with a locking member configured to hold one or more containers in a secure, transportable, and closed fashion. The rack includes a platform having a plurality of slots sized and shaped to accept containers of various sizes, with each slot having at least one locking member associated with it to form a locking groove. The locking member and platform form the locking groove which is adapted to secure a container in the rack in an upright and stable position. Advantageously, when containers having lids are in the locked position within the rack, the locking member makes contact with the lid to keep the lid in its closed position.

Abstract: The present invention provides a sample container holder for securely holding sample containers of various shapes and sizes. The holder comprises a base having at least one slot extending from an upper portion of the base to a lower portion of the base. The holder further comprises at least one retainer inserted into the slot creating at least a partial enclosed area on the base to accommodate the sample container.

Abstract: A spherical vacuum desiccator consists of two substantially identical shells which are connected together at an engagement region. A receiving segment and connecting segment are positioned in a spaced-apart relationship within the engaging region of each hemispherical shell. In the assembled condition of the invention, each hemispherical shell is disposed in an inverted position with respect to the other shell and the connecting segment of the two hemispherical shells engage at the receiving segment.
