Provided are a microparticle sorting device, and a method and a program for sorting microparticles capable of stabilizing sorting performance over a prolonged period of time. The microparticle sorting device includes an imaging element and a controller. The imaging element obtains an image of fluid and fluid droplets at a position where the fluid discharged from an orifice which generates a fluid stream is converted into the fluid droplets. The controller controls driving voltage of an oscillation element which gives oscillation to the orifice and/or controls a position of the imaging element based on a state of the fluid in the image and/or a state of a satellite fluid droplet. The satellite fluid droplet does not include microparticles and exists between the position, where the fluid is converted into the fluid droplets, and a fluid droplet, among fluid droplets including the microparticles, which is closest to the position where the fluid is converted into the fluid droplets.

There is provided a microparticle sorting method including a procedure of collecting a microparticle in a fluid that flows through a main channel in a branch channel that is in communication with the main channel by generating a negative pressure in the branch channel. In the procedure, a flow of a fluid is formed that flows toward a side of the main channel from a side of the branch channel at a communication opening between the main channel and the branch channel.

Disclosed herein is a acoustic concentration of particles in a fluid flow that includes a substantially acoustically transparent membrane and a vibration generator that define a fluid flow path therebetween. The fluid flow path is in fluid communication with a fluid source and a fluid outlet and the vibration generator is disposed adjacent the fluid flow path and is capable of producing an acoustic field in the fluid flow path. The acoustic field produces at least one pressure minima in the fluid flow path at a predetermined location within the fluid flow path and forces predetermined particles in the fluid flow path to the at least one pressure minima.

A pickup location that includes a control station and one or more storage compartment modules provides the ability for items to be ordered and delivered for pickup by a user without having to pack those items in a shipping package prior to shipping from a materials handling facility. Delivering items for pickup by a user without having to package the items prior to shipping, may provide a better experience for the customer, reduce waste in packaging material and a lower cost of delivering the ordered items to the customer.

Provided is a raw material supply device and a device for processing electronic and electrical device part scraps, which can control dropping positions of a raw material containing substances having different shapes and specific gravities, as well as a method for processing electronic and electrical device part scraps using those devices. A raw material supply device 4 includes an accommodating portion 41 for feeding a raw material 100 to a predetermined position, wherein the raw material supply device 4 includes: a receiving port 43 having a first opening 433 for receiving the raw material 100 on a top surface of the accommodation portion 41; a discharge port 42 having a second opening 422 for discharging the raw material 100 on a bottom surface of the accommodating portion 41, the second opening 422 having a cross-sectional area lower than that of the first opening 433; a first guide surface 412 in a front of a side surface of the accommodating portion 41, the first guide surface 412 extending in a vertical direction through the discharge port 42 from the receiving port 43 so as to be contacted with the raw material 100 dropped toward a front of a conveying unit 2 to guide the raw material 100 downward; and a second guide surface 411 on a surface opposing to the first guide surface 412, of the side surface of the accommodating portion 41, the second guide surface 411 being provided with an inclined surface 411a that is continuous with the discharge port 42 and is inclined with respect to a horizontal plane, and wherein the first guide surface 412 extends such that a lowermost end portion of the first guide surface 412 is located below an intersection P of an extended line extending in an inclination direction of the second guide surface 411 with the first guide surface 412.

A method for operating a robot includes providing target data for a target object; determining whether a pre-pick target for the target object is reachable by the robot; determining whether a pick target is reachable by the robot; and executing a pick routine directing the robot to pick up the target object and deposit the target object at a desired location responsive to a determination that the pre-pick target and the pick target are reachable by the robot.
