High current electrical joint that eliminates partial assembly
An electric joint formed between a high current source and a high current load, and a method of making electrical connection between them. In one form, the source is made up of one or more cells in a battery pack and the load is an electric motor. An electrical connection assembly includes a first conductor, a fastener and a second conductor joined together such that electrical continuity between the conductors is not established until the fastener imparts a substantially normal force to both of them in such a way that they become secured together to produce a deformable shape to adjacently-facing surfaces one or both conductors, thereby ensuring significant contact and a related low electrical resistance as a way to avoid imperfect or partial attachments at the joint. |

Electronic device and battery accommodating module
A battery accommodating module is used for accommodating a battery. The battery accommodating module includes a battery case and a latch member. The battery case has an accommodating space and a side of the battery case has two pivot holes and at least one first restraining portion. The latch member has two pivot portions and at least one second restraining portion, wherein the pivot portions are pivotally connected to the pivot holes, such that the latch member can rotate with respect to the battery case between a lock position and an unlock position. When the latch member is located at the unlock position, the first restraining portion keeps the second restraining portion at a first side of the first restraining portion. When the latch member is located at the lock position, the first restraining portion keeps the second restraining portion at a second side of the first restraining portion. |

Encapsulation layer thickness regulation in light emitting device
An ink jet process is used to deposit a material layer to a desired thickness. Layout data is converted to per-cell grayscale values, each representing ink volume to be locally delivered. The grayscale values are used to generate a halftone pattern to deliver variable ink volume (and thickness) to the substrate. The halftoning provides for a relatively continuous layer (e.g., without unintended gaps or holes) while providing for variable volume and, thus, contributes to variable ink/material buildup to achieve desired thickness. The ink is jetted as liquid or aerosol that suspends material used to form the material layer, for example, an organic material used to form an encapsulation layer for a flat panel device. The deposited layer is then cured or otherwise finished to complete the process. |
