Abstract: A method includes: obtaining a batch of item group definitions, each item group definition having one or more item identifiers and corresponding quantities; for each item identifier, retrieving (i) a location of a corresponding item in a facility, and (ii) a dimensional attribute of the corresponding item; based on the locations and dimensional attributes, assigning sets of the item group definitions to respective receptacle configurations, each receptacle configuration including, for each item group definition in the set, a receptacle type with a predefined capacity; monitoring availability of a plurality of transporters in the facility, each transporter having a chassis configured to support a selectable set of receptacles; and responsive to detecting that a transporter is available, selecting one of the receptacle configurations, and presenting the selected receptacle configuration via an output device, to initiate placement of receptacles onto the chassis of the transporter according to the selected recep

Abstract: A collinear antenna assembly and a series-fed omnidirectional collinear antenna array are provided. The collinear antenna assembly includes a plurality of phase delayers connected in series, and an end portion of each phase delayer is connected to an antenna radiating unit; the phase delayer includes a circuit wire printed on a dielectric plate, two ends of the circuit wire are connected to the antenna radiating unit, a wire length, a wire width and a wire spacing of the circuit wire are set based on preset wiring rules, the wire lengths, the wire widths and the wire spacing of the circuit wires of the phase delayers set based on different preset wiring rules are different, so that a phase and an amplitude fed to each antenna radiating unit are accurately controlled.

Abstract: An otoscopic accessory for use in performing procedures in the external auditory canal and middle ear space, having a speculum, a probe and an actuator. The speculum has a generally tapered sidewall. The proximal end of the sidewall is configured to engage the head of an otoscope, and the distal end of the sidewall is configured to be inserted into a patient's outer ear canal. The probe has a shaft that is positioned against an exterior surface of the sidewall of the speculum. The actuator is coupled at its distal portion to the speculum. The distal portion of the actuator is closely conformed to the proximal end of the sidewall of the speculum to form a guide between the exterior surface of the speculum and the distal portion of the actuator. The probe is positioned within the guide, and the guide directs the distal end of the probe to a location within or on the distal end of the sidewall of the speculum. The probe is fixed to and moves with the proximal portion of the actuator.

Abstract: A computer system having a processor-cache protocol supporting multiple cache configurations is described. The computer system has a processor having a cache control circuit to control multiple cache memory circuits. The processor including its cache control circuit is coupled to a cache bus. A second level cache memory is also coupled to the cache bus. The cache control circuit controls the second level cache by issuing commands that are executed by the second level cache.
