Abstract: In some examples, a structure is contacted with polynucleotides having a variety of lengths and each including first and second adapters. The structure includes a substrate including first and second regions spaced apart from one another by a gap of at least 100 nm, a first set of capture primers coupled to the first region of the substrate, and a second set of capture primers coupled to the second region of the substrate. The first adapter of the polynucleotide is hybridized to a capture primer of the first set of capture primers. Based on that polynucleotide being sufficiently long to bridge the gap, it is amplified using the first and second sets of capture primers. Based upon that polynucleotide being insufficiently long to bridge the gap, it is not amplified. Optionally, a wall may be disposed in the gap.

Abstract: A cable for connecting a medical imaging device to a medical imaging controller includes a first connector located at a distal end of the cable for connecting to the imaging device, a second connector located at a proximal end for connecting to the medical imaging controller, a circuit board comprising at least one memory that stores at least authentication information associated with the cable. The circuit board is communicatively connected via a communication bus on the circuit board to the second connector for enabling access to the authentication information by the medical imaging controller. One or more imaging communication lines extend between the first connector and the second connector for communicating imaging data from the medical imaging device to the medical imaging controller. The one or more imaging communication lines bypass the communication bus on the circuit board.

Abstract: A patient support apparatus system includes sensors adapted to sense a gesture of a person, or forces exerted by the person on the patient support apparatus, and to control the movement of a component of the patient support apparatus based on the gesture or forces. The movement of the patient support apparatus matches the direction of the person's gesture or applied forces. The speed of the gesture and magnitude of the applied force also influence the movement of the patient support apparatus component. The controlled movement may be the upward and downward motion of a patient support deck on the patient support apparatus, or it may be the pivoting of a section of the patient support deck, or it may be other movement. Control of the patient support apparatus is carried out based on the intent of the user, as evidenced by the user's gesture or applied forces.
