Abstract: The present invention relates to the application of a force to enhance the performance of an electrochemical cell. The force may comprise, in some instances, an anisotropic force with a component normal to an active surface of the anode of the electrochemical cell. In the embodiments described herein, electrochemical cells (e.g., rechargeable batteries) may undergo a charge/discharge cycle involving deposition of metal (e.g., lithium metal) on a surface of the anode upon charging and reaction of the metal on the anode surface, wherein the metal diffuses from the anode surface, upon discharging. The uniformity with which the metal is deposited on the anode may affect cell performance. For example, when lithium metal is redeposited on an anode, it may, in some cases, deposit unevenly forming a rough surface. The roughened surface may increase the amount of lithium metal available for undesired chemical reactions which may result in decreased cycling lifetime and/or poor cell performance.

Abstract: A system according to one embodiment includes a first computing device comprising ultra-wideband communication circuitry, and a second computing device comprising ultra-wideband communication circuitry configured to communicate with the ultra-wideband communication circuitry of the first computing device to determine the angle and distance of the first computing device relative to the second computing device.

Abstract: A connecting rod for changing a compression ratio of an internal combustion engine includes a connecting rod head, a connecting rod pin, and an interlock. The connecting rod pin is supported by an eccentric of the connecting rod at a variable distance within the connecting rod head. The connecting rod head or the connecting rod pin includes a fluid chamber and the eccentric has a projection extending into the fluid chamber. In the alternative, the eccentric delimits a fluid chamber and the connecting rod head or the eccentric has a projection extending into in the fluid chamber. A fluid pressure in the fluid chamber exerts a force on the projection to change the position of the eccentric. In a locking position, the interlock inhibits rotation of the eccentric relative to the connecting rod head and the interlock is configured to be releasable.

Abstract: The connecting rod head includes at least one oil chamber and an eccentric comprises a protrusion reaching into the oil chamber, so that an oil pressure in the oil chamber exerts a force on the protrusion to change the eccentric setting of the eccentric.

Abstract: The invention relates to a device for changing a compression ratio of an internal combustion engine. The device comprises a connecting-rod head (1) with an eccentric bearing (2), an eccentric (3) which is mounted rotatably in the eccentric bearing (2) and which comprises a piston pin bearing (3), a piston pin (5) which is mounted rotatably in the piston pin bearing such that, by means of rotation of the eccentric the position of the piston pin relative to the connecting rod head (1) can be adjusted from a top dead centre to a bottom dead centre and vice versa, and a locking device (8) for locking the eccentric at the top dead centre.
