The present invention relates to an internal fixing device for an apparatus in a transport mode, an apparatus comprising said device, and a method for reducing the risk of damage to the apparatus during transport. The internal fixing device comprises a limiting device, eccentric roller transmission assemblies, a motor assembly, a motion guide assembly, etc. The two ends of a motor output shaft are fixedly disposed on eccentric roller transmission assemblies on two sides of the apparatus. By triggering a microswitch on the limiting device, eccentric rollers and rocking handles form self locking in a transport mode to stop motion. The present invention can effectively reduce the risk of damage to the apparatus during transport.

A method for measuring optical signal detector performance that includes directing light emitted from an optical signal detector onto a first non-fluorescent surface portion in a first detection zone of the optical signal detector. A first characteristic of light detected by a first sensor of the first optical signal detector is measured while the first non-fluorescent surface portion is in the first detection zone of the optical signal detector. Light emitted from the optical signal detector is directed into a first void in the first detection zone of the optical signal detector. A second characteristic of light detected by the first sensor of the optical signal detector is measured while the first void is in the first detection zone of the optical signal detector. And an operational performance status of the optical signal detector is determined based on at least one of the first characteristic and the second characteristic.

A dispensing apparatus that sucks and discharges liquid through a tip includes a motor, a tip attaching and detaching unit allowing attachment and detachment of a plurality of the tips, a tip holder that holds the plurality of tips, a support member that supports the tip attaching and detaching unit in a displaceable manner, and a drive transmitter that transmits a driving force of the motor to the support member. The drive transmitter includes a transmission switch that switches the drive transmitter from a transmission state in which the driving force of the motor is transmitted to a non-transmission state in which transmission of the driving force of the motor is blocked when an overload on the motor exceeds an upper limit value in a case where the plurality of tips held by the tip holder is attached to the tip attaching and detaching unit along with a displacement of a position of the tip attaching and detaching unit.

A power off delay system and method is configured to delay termination of electrical power to a digital pathology device in a power off condition. If the apparatus includes a UPS, the power off delay system and method delays termination of electrical power when a power switch is turned off and when a catastrophic power failure occurs. During the delay of the termination of electrical power, the digital pathology device is configured to control the scanning stage system and the glass slide conveyor system and the slide rack conveyor system to place each of these systems into a known state and position all glass slides into a known position prior to the termination of electrical power to the digital pathology device. This allows the digital pathology device to resume normal operation upon power up.

The present application describes a new device and method of use thereof, which allows identifying certain antigens and antibodies present in the blood. The device of the present invention is a closed device consisting of two parts, wherein the upper part has a chamber surrounded by LEDs illuminating the analysis plate, which is supported by the rotating platform. In turn, the rotating platform is connected to a motor that will promote the rotation thereof for mixing reagents with blood. After a period of time, the camera will capture and send the resulting image to a computer program that will analyze the sample, using image processing techniques.

A pipette tip supply mechanism includes: a pipette tip storage unit for storing a plurality of tapered shaped pipette tips; a belt for transporting a pipette tip supplied from an opening of the pipette tip storage unit; and a belt drive unit that drives the belt in a transport direction.
