Abstract: Apparatus, systems and methods for ascertaining the occupancy of a building are presented. The building is divided into one or more control zones which correspond to physical areas of the building associated with controllable modules, such as HVAC units, lighting, irrigation, or other environmental features such as fountains, music, video, and the like. Zone parameters define how zone devices shall react to the number of occupants located in the particular zone. A building control system detects individual mobile devices in and around the building, and determines the locations of each device by using trilateration and/or location services. The identified mobile devices act as proxies for building occupants. The locations of these devices are correlated with the locations of the zones in the building, and the building control system then adjusts the operating parameters of the zone based on the number of devices present in the zone.

Abstract: A furniture system is provided having a support to be mounted to an upright structure of a building, and a shelf that is assembled onto the support. The shelf has a load-bearing surface, a front side, and a rear side with a first connector. The support has an outer face that includes at least one second connector. The first and second connectors are configured to interconnect such that, in the assembled the furniture system, the shelf is supported by the support with the load bearing surface projecting horizontally away from the upright structure, the first and second connectors resist rotation of the shelf about the first and second connectors by a force acting downwardly through the load bearing surface, and the first and second connectors resist disconnection of the shelf from the support by force applied to the shelf in a direction that is normal to the support.

Abstract: A method of generating text features from a document comprises one or more processors grouping text comprised in the document into multiple logical text blocks, wherein each of the logical text blocks comprises one or more tokens. One of the logical text blocks is selected for generating features. Thereafter, logical text blocks neighbouring the selected logical block are identified. Further, the processer qualifies one or more of the neighbouring logical text blocks for generating features. The processor generates features for one or more of the tokens in the selected logical block using the qualified logical text blocks.

The thermoelectric device is made from a first substrate and a second substrate, each including an n-type and p-type thermoelectric legs. The first and the second substrate are brought together so that the n-type and p-type thermoelectric legs of the first substrate come into direct contact with, respectively, the n-type and the p-type thermoelectric legs of the second substrate. Each thermoelectric leg may be disposed in a well formed in an insulating layer disposed over contact electrodes supported on the first and second substrate. Each thermoelectric leg may contain a particulate semiconductor and a binder, e.g. a polymer binder. The pairs of legs are bonded together by heat curing.

Abstract: Systems, methods, and computer program products are disclosed for correlating merchant ratings to tipping amounts. In a generalized method, a merchant rating is entered by a user via a user interface. Based upon the merchant rating, the system determines a merchant tip amount, which is then communicated to the user via the interface. Accordingly, merchant ratings and tips are seamlessly integrated with one another.

Abstract: A method of manufacturing a conductive layer includes the step of dissolving an organic semiconductor polymer in a first solvent, the first solvent being an aromatic or heterocyclic compound comprising one or more electron-rich carbon atom(s) and/or heteroatom(s). The method also includes dissolving a dopant in a second solvent, the second solvent being a polar solvent. The method also includes mixing the solutions of the organic semiconductor polymer and the dopant to form a dispersion comprising doped conductive polymer particles suspended in the solvent blend. The method also includes depositing the dispersion by a solution deposition technique to form a conductive layer. The solution deposition technique is preferably an inkjet printing, dispense printing or drop casting method. The dispersion provides a stable ink composition for the manufacturing of thick and uniform layers with excellent conductivity and thermopower, and allows simple fabrication of thermoelectric legs with enhanced performance.
