A weight lifting apparatus having a weight lifting bar, and in some cases, a weight lifting stand configured to support the weight lifting bar, is described. The weight lifting bar is a linearly contiguous bar having a neck wrap portion, two elongated members extending down approximately an arm’s length from the neck wrap portion to at least the waist of a lifter and weight posts. Linearly contiguous means that the primary bar components, including the neck warp portion, elongated members and weight posts, are all part of a single connected bar having a length and a first end and second end. The weight lifting apparatus may comprise a stand configured to support the weight lifting bar. A stand may comprise a main portion, a step-up platform and a weight lifting bar support comprising two support members extending from the main portion or the step-up platform, and a bar rest.

The present application describes, among other things, a battery management system. The battery management system includes a computing device and first and second battery unit monitoring modules. The computing device includes an output data request port and an input data port. Each battery unit monitoring module is connected in parallel to the input data port of the computing device. In response to a data request from the output data request port of the computing device, the first battery unit monitoring module transmits data of the first battery unit to the input data port of the computing device, and transmits a data request to the second battery unit monitoring module. In response to the data request from the first battery unit monitoring module, the second battery unit monitoring module transmits data of the second battery unit to the input data port of the computing device.

An electrical machine stator assembly comprises: an electroconductive coil arranged circumferentially with respect to the rotational axis; a plurality of pairs of side lamination assemblies arranged circumferentially with respect to the rotational axis; a plurality of pairs of switch lamination assemblies arranged circumferentially with respect to the rotational axis and positioned adjacent ends of side lamination assemblies proximal the rotor; and at least one tooth associated with each switch lamination assembly and proximal the rotor. Each switch lamination assembly comprises a first group of laminated materials aligned generally circumferentially and generally in a first direction with respect to the rotational axis, the first direction being one selected from the group consisting of the axial and radial directions with respect to the rotational axis. Each side lamination assembly comprises a second group of laminated materials aligned generally axially and generally radially with respect to the rotational axis.

A adjustable Hall effect sensor system having a sensor positioning component is described. In one embodiment, the Hall effect sensor system is an independently adjustable sensor system, having a plurality of Hall effect sensor, wherein one Hall effect sensor may be displaced and adjusted without effecting the location of another Hall effect sensor. A sensor positioning component comprising a paddle coupled to a main body portion by a more narrow neck is described. A cam may be configured on a paddle and provide for fine tuning the position of a Hall effect sensor. In one embodiment the main body and extensions are comprised essentially of a circuit board.

Electrical machines, for example transverse flux machines and/or commutated flux machines, may be configured to achieve increased efficiency, increased output torque, and/or reduced operating losses via use of laminated materials in connection with powdered metal materials. For example, stacks of laminated materials may be coupled to powdered metal teeth to form portions of a stator in an electrical machine.

A formable handle toothbrush has a handle portion that allows a user to heat and form the handle to the shape of their hand to provide for more secure grip of the toothbrush. In one embodiment, a hand formable toothbrush has a toothbrush head attached to a shank that can be inserted into a socket within the toothbrush handle. This configuration allows for the use of replacement toothbrush heads. This makes manufacturing of higher cost handles more economical, as the formable handle portions would not be thrown out when the toothbrush head needs replacement. To customize the formable handle portion, a user may simply place the toothbrush, or handle portion of the toothbrush, in boiling water for a period of time and then remove the toothbrush handle, allow it to cool to a safe temperature and then grasp the handle to form it into the shape of their hand.
