  • Patent number: 10075612
    Abstract: A multi-function print server administration service implemented on a server computer receives a request, by a user associated with either a vendor-administrator user account or a system administrator account, to modify a first set of one or more application services enabled on one or more multi-function print devices associated with the vendor-administrator user account. In response to receiving the requests, the multi-function print server generates a modified first set of one or more application services, which implements a modification to the one or more application services based on the received request to modify the first set of one or more application services. The multi-function print server administration service enables the modified first set of one or more application services on the one or more multi-function print devices.

  • Publication number: 20180240116
    Abstract: A server transaction processing service implemented on the apparatus receives requests to authorize user sessions on multi-function print devices. A server application service implemented on the apparatus receives service task requests, which are requests for services that may be at least partially performed at one or more external servers. The application service then sends the service task requests to the appropriate external servers. The transaction processing service receives requests to end active user sessions. Then the transaction processing service is configured to determine whether any service task requests from user sessions were unsuccessfully executed and generate a subset of unsuccessfully executed service task requests. The transaction processing service may generate refund requests for each user session that contained unsuccessfully executed service task requests and send the refund requests to an authorization and capture service for processing.

  • Patent number: 10038002
    Abstract: Some embodiments include a semiconductor device having a stack structure including a source comprising polysilicon, an etch stop of oxide on the source, a select gate source on the etch stop, a charge storage structure over the select gate source, and a select gate drain over the charge storage structure. The semiconductor device may further include an opening extending vertically into the stack structure to a level adjacent to the source. A channel comprising polysilicon may be formed on a side surface and a bottom surface of the opening. The channel may contact the source at a lower portion of the opening, and may be laterally separated from the charge storage structure by a tunnel oxide. A width of the channel adjacent to the select gate source is greater than a width of the channel adjacent to the select gate drain.

  • Patent number: 10025901
    Abstract: An approach is provided for acquiring and integrating data into external services. According to the approach, image and/or video data and identification data are received from a client device. The image and/or video data includes one or more images and/or video data of an object that are acquired by the client device and the identification data is data that uniquely identifies the object. Record data is generated and stored that includes the identification data and at least a reference to the image and/or video data. The image and/or video data and the identification data are transmitted to an external service. This identification data allows an external service to associate the image and/or video data with other data maintained by the external service.

  • Patent number: 9985046
    Abstract: A linear mark extending perpendicular to a primary step direction of stepped terrace for a three-dimensional memory device can be employed as a reference feature for aligning a trimming material layer before initiating an etch-and-trim process sequence. The linear mark can be formed as a linear trench or a linear rail structure. The distance between a sidewall of each trimming material layer and the linear mark can be measured at multiple locations that are laterally spaced apart perpendicular to the primary step direction to provide statistically significant data points, which can be employed to provide an enhanced control of the staircase patterning process. Likewise, locations of patterned stepped surfaces can be measured at multiple locations to provide enhanced control of the locations of vertical steps in the stepped terrace.

  • Patent number: 9885147
    Abstract: A stain-barrier is described along with methods of its application to a fabric. The stain barrier can be applied to fabric samples and limits the amount of fabric with which deposited liquid is able to interact. This stain barrier reduces unwanted variability between samples of different dilution or fabric type so that limits of stain detection can be assigned more accurately and precisely and stain detection techniques can be transparently compared.
