  • Patent number: 8870974
    Abstract: A method of fabricating a battery comprises selecting a battery substrate having cleavage planes, and depositing on the battery substrate, one or more battery component films comprising electrode films that at least partially surround an electrolyte film. Pulsed laser beam bursts are applied to the battery component films at a sufficiently high power level to vaporize portions of the films to form shaped battery features. The pulsed laser bursts shape the films substantially without causing fractures along the cleavage planes of the battery substrate. Pulsed laser shaping can be used to replace the use of a mask in the fabrication of shaped battery components.

  • Patent number: 8868746
    Abstract: Described is a method for allocating a central application resource. Upon a determination that a user has depleted an allocation of the resource, a request for an additional allocation of the resource is generated. The user is a member of a group of users that is a subset of all users of the central application resource. After determining that the request is valid according to a policy defining rules for allocation relevant to the user, the additional allocation is provided to the user. An allocation of the resource is reduced for one or more other users in the group so that a total allocation of the resource for the group remains unchanged.

  • Publication number: 20140207564
    Abstract: A system and methods are provided for serving content in response to content queries or requests. When a request is received, for content to be presented to a specified user, candidate content items are identified, possibly based on matches between attributes of the user and attributes of the items' target audiences. For each item, a history indicating the frequency (e.g., total number) and/or recency with which impressions of the candidate item were previously presented to the user is retrieved and used to determine a modifier value, which is applied to a calculated or generated probable click-through-rate (pCTR) to produce a modified probability that the user would act on the item if it is served to him or her. Each item's estimated value is computed by multiplying a bid associated with the item and the modified probability; the results are ranked and the top-ranked item(s) are served.

  • Patent number: 8780776
    Abstract: Realization of sleep and reconnecting functions is developed for network systems which comprise a number of end devices, network path sharing devices and coordinators. End devices and, even, network path sharing devices can be enforced to enter a sleep state at the first preset times and wake up at the second preset times. The two preset times are either assigned offline or adjustable at run time, according to the actual traffic load in the network. When a node wakes up, it checks whether the corresponding parent node is in the active state or not. If the corresponding parent node is not in the active state, the node will find a new parent node to establish a new transmission path.

  • Publication number: 20140178078
    Abstract: There is provided a method of eliminating an offset in a spot centroid due to crosstalk. A crosstalk matrix is used to characterize crosstalk characteristics of a multi-pixel spot-centroid detector. Left-multiplication of signals outputted from the multi-pixel spot-centroid detector, which are affected by the crosstalk, by an inverse matrix of the crosstalk matrix can result in a light-intensity-distribution signal with impacts of the crosstalk substantially removed. Based on this light-intensity-distribution signal, it is possible to derive the spot centroid, with the offset in the spot centroid due to the crosstalk substantially eliminated, resulting in an improved accuracy of the spot centroid detection, as compared with conventional methods.
