The invention relates to a power storage module (10) capable of containing a plurality of power storage elements (14), the module including: a housing (16) including at least a plurality of side walls and two end walls (18A; 18B), the side walls consisting of one piece (20) having a closed outline and being sized so as to surround the power storage elements; a wall (22) for supporting the power storage elements, which is separate from the walls of the housing, and which extends essentially parallel to one of the side walls, referred to as a reference wall (20A); a means (24A-24B) for changing the position of the supporting wall (22) between at least an assembly position, in which the supporting wall is located at a first distance from the reference wall (20A), and an operating position, in which the supporting wall is located at a second distance from the reference wall (20A) that is greater than the first distance.

An apparatus for testing a battery-powered device is provided. The apparatus is configured to be inserted into a button cell battery slot of the device to provide temporary power for testing the device. The testing apparatus may include a button cell battery, electrical contacts connected to or provided by the button cell battery and configured to engage electrical contacts within the button cell battery slot of the device, and an extension portion shaped to project from the slot when the testing apparatus is inserted into the button battery slot.

The present disclosure provides a charging system comprising a first charging module and a second charging module. The first charging module comprises a first charging electrode, a second charging electrode, a charge controller and at least one rechargeable battery. The first charging electrode and the second charging electrode are coupled to the charge controller. The charge controller is coupled to the rechargeable battery. The second charging electrode is substantially annular, and the first charging electrode is surrounded by the second charging electrode. The second charging module comprises a first dock electrode, a second dock electrode and a battery charger. When the first charging module and the second charging module are electrically coupled, the first charging electrode is electrically coupled to the first dock electrode, and the second charging electrode is electrically coupled to the second dock electrode.

In one aspect, the present invention is directed to a rolling box apparatus, comprising: a cover (12) pivotally connected to a box (10) thereof by a pivot (42); a strap (16), for rolling a cigarette; a LED (20), for illuminating the strap; a battery (44), for providing power to the LED; a circuit (46), for connecting the LED (20) to the battery (44); the circuit (46) comprising a switch (22) activated by the cover (12), for closing the circuit upon opening the cover (12), and opening the circuit upon closing the cover; thereby illuminating the strap upon rolling a cigarette.

A security tag including: a housing and circuitry which detects a locked state, the circuitry configured to execute a signal transfer function responsive to interchanging a pin and a lanyard in the circuitry, and/or the housing including a replaceable battery compartment locked by inserting either the pin or the lanyard into a lock mechanism which differently secures the pin and the lanyard; and an alarm, in communication with the circuitry, triggered by an undisarmed breach of the locked state.

The battery unit (1) includes a flat battery (2) having a cylindrical positive electrode can (10) with a bottom and a cylindrical negative electrode can (20) with a bottom that covers an opening side of the positive electrode can and having a side wall of the positive electrode can on the opening side fitted to an outer circumferential surface of a side wall of the negative electrode can and a substrate (61) provided on a flat surface of one of the negative electrode can and the positive electrode can and mounted with circuit components (62) thereon. The other of the negative electrode can and the positive electrode can that has a flat surface on an opposite side to the substrate in a thickness-wise direction of the flat battery serves as an external terminal for one of a positive electrode and a negative electrode.

A molded housing of a conformal wearable battery (CWB) encloses an electronic component and include an electrically conductive contact component embedded within an exterior wall to conduct electricity between an interior and an exterior of the casing. A flexible printed circuit board assembly (PCBA) for a conformal wearable battery (CWB) is enclosed in a cavity within the molded housing and includes attachment sections for a plurality of battery cells that are arranged in a grid-like pattern on a same side of the flexible PCBA. A visco-elastic shock-absorbing member installed between the upper and lower portion of the flexible PCBA when configured in a folded configuration. Each battery cell is joined to the flexible PCBA via a welding process. Each battery cell has a visco-elastic shock-absorbing member attached individually to each battery cell of the plurality of battery cells. When folded to fit within the cavity of the molded housing, the flexible PCBA forms a three-dimensional grid of physical components comprising at least the battery cell modules.

A drug delivery device comprising a first module comprising a zinc-air cell located at one end of the first module, a second module for attachment to the one end of the first module and comprising electronics, and activation means for activating the zinc-air cell and being designed such that at least one air hole is created in an air tight sealing of the zinc-air cell when the second module is attached to the one end of the first module.
