Abstract: An apparatus for dispensing small objects is disclosed. The apparatus includes a frame forming an upper chamber and a lower chamber. The frame supports a rotatable barrel that is disposed between the chambers. The barrel is constructed from a folded rectangular sheet that forms a chamber with an opening. The rotatable barrel is oriented with the opening facing upward to receive objects from the upper chamber into the barrel's chamber, such that when the handle is rotated about a horizontal axis the barrel turns to orient the opening downward and deposit objects in the barrel's chamber into the lower chamber.

Abstract: Various technologies described herein pertain to delivering shared WiFi credentials. According to various embodiments, at least one server computing device is configured to transmit shared WiFi credentials to a mobile device. The at least one server computing device receives a request, where the request includes data that identifies the mobile device. Moreover, the request indicates that the mobile device desirably receives credentials for a shared WiFi network. Responsive to receiving the request, the at least one server computing device determines that the mobile device is authorized to receive the credentials for the shared WiFi network based at least in part upon the data that identifies the mobile device. Moreover, the at least one server computing device transmits the credentials for the shared WiFi network to the mobile device responsive to determining that the mobile device is authorized to receive the credentials for the shared WiFi network.

Abstract: Embodiments apply a set of sequenced instructions to connect to a network through a captive portal. A computing device detects a network access point and obtains the instruction set corresponding to the network access point. The instruction set is derived by a cloud service from crowdsourced data describing interactions between mobile computing devices and the network access point. Applying the instruction set includes performing actions such as navigating web pages to accept terms and conditions, provide user or device information, and more.

Abstract: A planar dipole antenna for dual-band Wi-Fi application is disclosed. The antenna has a ground copper and a radiation copper. The ground copper is adhered to a substrate and has an upper, shorter and generally horizontal segment and a lower, longer and also generally horizontal segment that are connected at one end thereof by a vertical segment. The radiation copper is adhered to the substrate and has a copper shaped substantially as a mirror symmetry of the ground copper and spaced apart from the ground copper by a gap at the end of the ground and radiation coppers where the shorter and longer horizontal segments thereof are connected. The antenna has a gross span of approximately 42 mm and a height of approximately 7 mm. The gap is approximately 0.

Abstract: A modular refrigeration unit (12) for use in an accessible compartment (37) of a cooler. The modular refrigeration unit (12) includes a wire-frame support (50), a dividing wall (42) mounted to the wire-frame support (50), a condenser assembly (48) mounted to the wireframe support (50) on one side of the dividing wall (42), and an evaporator assembly (46) mounted to the opposite side of the dividing wall (42).

Abstract: It comprises three basic parts, a central part (1) which configures a type of pallet with metallic panels and crossbars, and two side parts (2-2?), physically independent from the central part and fixed to it with screws (14) and with its corresponding nuts. This way the pallet can be stored and carried independently, this is the side parts (2-2?) are physically independent from the central part (1), using a minimum space but at the same time it can be easily assembled with the help of the screws when so required. It is different from other supports in that in conventional supports the structure is rigid and impossible to dismantle, and therefore it occupies a considerable space when it is used for storage and transport.

Abstract: The invention is an automated multiple-purpose, integrated laboratory system comprising interchangeable modular elements for the construction and measurement of biological assays. The functions of the modular elements may include multiwell platform handling, chemical reagent or cell management, volumetric transfer of liquids for assay construction or for recovery of reaction products for analysis, incubation under controlled environmental conditions, measurement of spectrometric signals originating from the assays, processing and analysis of the resulting spectrometric data, and other functions. The modular elements are arranged around a number of robotic elements that deliver plates to different modular elements, transfer plates to groups of modules served by a different robotic element, or other actions necessary in plate handling.

Abstract: A liquid level sensor comprises a plurality of electrodes arranged in a defined relationship with respect to a container filling trajectory, a signal generator coupled to one or more of the plurality of electrodes, a signal receiver coupled to one or more of the plurality of electrodes, and a sensing circuit coupled to at least one of the signal generator and signal receiver. The sensing circuit is configured to produce an output indicative of electrical resistance between at least one pair of the plurality of electrodes. The sensing circuit may be associated with the signal receiver and/or with the signal generator.

Abstract: Disclosed herein are systems and methods for detecting motion of an object, such as the paw of rat. A tag comprising an inductive element and a capacitive element may be attached to the object and the motion detected by monitoring the affect of the tag on a time-varying magnetic field.

Abstract: A device for characterizing the biological properties of cells can include a plurality of dual-compartment assay chambers wherein the compartments of each chamber are separated by a cell layer across which ions can flow. The biological properties of the cell layer in the presence or absence of experimental compounds can be determined by measuring an electrical gradient across the layer. A individual dual-compartment chamber of this type may be referred to as an “Ussing chamber.

Abstract: A method and apparatus is disclosed for automated on-the-fly dispensing of reagents. The apparatus includes a detachable reagent dispensing module supported by a support frame. The dispensing module includes a self-contained pressurized fluid delivery subsystem that facilitates efficient attachment and detachment of the module, including pressurized reagent containers and associated accessories arranged such that each reagent container has a discrete fluid path terminating at a corresponding discrete reagent dispensing tip. The dispensing tips are supported in a common dispensing head, and are arranged geometrically such that the centers of the dispensing tips are separated by distances corresponding to relevant dimensions of particular assay plates to be used therewith. Such a geometric arrangement allows for dispensing of multiple reagents substantially simultaneously into multiple corresponding target wells of the assay plate, efficiently and precisely.
