Abstract: A spill pallet including: a continuous, unitary, liftable sump-defining base having a bottom, side walls extending from and surrounding the bottom and terminating in an upper edge, a plurality of risers extending from the bottom, and a rim formed in the side walls below the upper edge; and at least one drum-supporting grate that is supportable on the plurality of risers and the rim of the base. Two fork channels that are accessible from a side of the base have a fork cavity height and a fork cavity width sufficient to permit the spill pallet to be lifted by a standard fork lift truck or by a standard pallet jack. The bases are configured such that they are stackable on and partially nestable within identical bases to form stacks, which can be shipped side-by-side as a partial load within a truck, trailer or container.

Abstract: A method to provide an order for a user to select goods includes automatically prompting a user via a voice command to collect an item from an order placed by a customer, and in response to receiving the input from an electronic device indicating that the item is unavailable, automatically prompting the user via a voice command to collect a substitute item designated, receiving an input indicating that the substitute item has been collected, followed by electronically notifying the customer that the substitute item has been collected instead of the original item. In another aspect, a voice-enabled click and collect system includes a remote server in communication with a mobile device, configured to prompt a user to collect an item, communicate the item unavailability to the remote server, receive instructions from the remote server, prompt the user to collect the substitute item, and notify the customer.

Abstract: A filter mask for use in a flow cytometer includes light blocking features and light passing apertures. The flow cytometer operates to evaluate one or more characteristics of a sample by illuminating the sample and a carrier fluid and collecting light rays that are radiated from the sample and the carrier fluid. The light rays are passed through the filter mask. The light blocking features of the filter mask are arranged to selectively block radiated light at certain radiation angles, while permit light rays having other radiation angles to pass therethrough. A sensor analyzer receives the light rays that pass through to evaluate at least one characteristic of the sample. The light rays can also be separated into two beams, which can be independently filtered using different filter masks. The results can then be compared to provide even more information regarding characteristics of the sample.

Abstract: A flow cytometer includes a flow nozzle, a light source, an optics system, and a sensor analyzer. The flow nozzle provides a fluid along a flow path. The light source generates a light beam that illuminates the fluid. The optics system collects light rays that are radiated from the light beam by the fluid and passes or blocks the light rays based at least in part on the radiation angles associated with the light rays.

Abstract: The present application discloses a thermal ground plane that is charged by laser welding a cover on an aperture. Prior to sealing, the thermal ground plane is filled with a quantity of a working fluid, and the device is heated until the working fluid is boiling in the cavity. Accordingly, the cavity is filled with the working fluid and with a saturated vapor of the working fluid. When the saturated vapor has displaced other gases, the cavity is laser welded shut.

Abstract: A system, method, and computer readable medium for electronic project and data management is described. The system is comprised of a central database, a server controller for the database, an interface with electronic access to the database for vendor and client personnel, and a foreman device. The device can create, view, and edit work-related documents, such as inspection checklists, and upload those documents to the database either contemporaneously or via manual synchronization. The device may also contain maps, a daily log, specifications, work codes, and project alerts. The interface provides access to project documents, member connections, and project alerts. Documents requiring approval automatically move through the chain of command as approved or rejected for revision. All members are automatically linked to project documents, and no paper is required for system operation. The method of carrying out the steps above is programmatically operated via a computer readable medium.
