Abstract: Light from a light source is directed at a flow path of particles of a flow cytometer. The directed light results in a light pattern having a plurality of lobes. A first signal is detected exceeding a first threshold. A second signal exceeding a second threshold is detected, wherein the second threshold is greater than the first threshold. Based on detecting the second trigger after detecting the first trigger, is determined that the first and second signals were created by a relatively large particle.

Abstract: An optically encoded message image is transmitted to a playing piece on an image display region of an image generating device. Position information relative to the position of the playing piece is sensed by the playing piece on the image display region. At least positional information is transmitted by the playing piece to the image generating device based on the sensed position information. The following is generated by the image generating device and displayed on the image display region: (1) an optically encoded message image only at the location of the playing piece as the playing piece moves over the image display region, the optically encoded message image including said position information, and (2) visual images elsewhere on the image display region.

Abstract: A baseplate assembly, used with releasably coupleable playing pieces, includes a baseplate operably coupled to an image generating device. The baseplate includes a display region, having playing pieces coupling elements, and means for transmitting images generated by the image generating device to the display region. An image generating and playing-piece-interacting assembly includes a receptor operably coupled to an image generating device, having a display screen for generated images, including integrated visual and optically encoded message images, a playing piece at a location relative to the display screen having an optical display message sensor, and a messaging transponder. The optical display message sensor receives the generated images and generates a first signal at least partially based upon the optically encoded message image. The messaging transponder receives the first signal and generates and sends the receptor a second signal at least partially based thereon.

Abstract: Fluid is flowed into an inlet channel of a microfluidic pathway at a flow rate, the microfluidic pathway including a first and second outlet channels fluidically connected to the inlet channel. A first cavitation bubble is created within the first outlet channel to block fluid flow out of the first outlet channel. A second cavitation bubble is created within the second outlet channel to block fluid flow out of the second outlet channel. Creation of the second cavitation bubble is initiated during or after the first cavitation bubble dissolves such that the flow rate is maintained.
