20150199667 | CLOUD-BASED POINT-OF-SALE PLATFORM - Disclosed herein are apparatus, method, and system embodiments for securing a cloud-based point-of-sale device. An embodiment includes a processing module and a communication module. The processing module is configured to operate with an operating system (OS) secured against alteration and to perform one or more purchase transactions. The communication module is configured to selectively enable acceptance of data via a secure communications path. | 07-16-2015 |
20150199668 | MULTI-MODE POINT-OF-SALE DEVICE - In an embodiment, a point of sale (POS) device is provided. The POS device includes a memory and at least one processor. The processor is configured to perform an authorized set of functions established by an external management module. The authorized set of functions include purchase transaction processing of inventory identified as available to the POS device by the external management module. | 07-16-2015 |
20150199882 | MULTI-MODE POINT-OF-SALE DEVICE - Disclosed herein are system, method, and computer program product embodiments for a cloud-based point-of-sale system and a multi-function point-of-sale (POS) device. In an embodiment, the POS device includes an interactive display that switches between a first position oriented towards and for use by an operating clerk, and a second position oriented towards and for use by a customer. The POS device is able to detect the switch between the first position and the second position. A processor in the POS device outputs a first graphical user interface (GUI) on the interactive display in response to detection of the first position and a second GUI in response to detection of the second position. In an embodiment, the components of the POS device are combined together in a unified assembly. | 07-16-2015 |

20150122324 | THIN-FILM PHOTOVOLTAIC DEVICE WITH OPTICAL FIELD CONFINEMENT AND METHOD FOR MAKING SAME - A photovoltaic device is provided that includes a first electrode layer and a second electrode layer; and a waveguiding structure disposed between the first electrode layer and the second electrode layer which includes an active layer adapted to convert photons transmitted to the active layer to electrons and holes. The waveguiding structure further includes a first layer adjacent the first electrode layer that includes a hole-conducting material having a first index of refraction, and a second layer including an electron-conducting material having a second index of refraction, wherein the active layer is disposed therebetween. The active layer has an index of refraction that is less than each of the first index of refraction and the second index of refraction and a thickness. The waveguiding structure is characterized by guided modes adapted for optically confining the photons within the active layer. | 05-07-2015 |

20140137978 | SYSTEM AND METHODS FOR USE IN DISPENSING BIOPHARMACEUTICAL MATERIALS - A pre-sterilized system for dispensing biopharmaceutical materials includes a reservoir for holding biopharmaceutical materials coupled to a filter and distribution manifold connected to a plurality of receiving containers. The manifold includes a plurality of container conduits and a plurality of distribution conduits. The plurality of container conduits is connected to the plurality of receiving containers and supports the plurality of distribution conduits above the plurality of receiving containers to allow flow of the biopharmaceutical materials from the plurality of distribution conduits by gravity into the plurality of receiving containers. The plurality of receiving containers and the manifold are sealed relative to an ambient environment outside the manifold and the plurality of containers to inhibit contamination of the biopharmaceutical materials when the biopharmaceutical materials are inside at least one of the plurality of receiving containers and the manifold. | 05-22-2014 |
