Abstract: Various techniques for delivering atrial pacing and supraventricular stimulation to achieve a desired ventricular rate and/or cardiac output are described. One example method described includes delivering a pacing signal configured to cause an atrial depolarization to a heart of a patient, wherein the atrial depolarization results in an associated refractory period during the cardiac cycle, and delivering a signal to a supraventricular portion of the heart of the patient subsequent to the atrial refractory period and during a ventricular refractory period of the cardiac cycle.

Abstract: An electrical connector includes an insulating body having a plurality of receiving slots and a plurality of terminals respectively fixed in the insulating body. Each of the terminals has a base at least partially disposed in the receiving slot, at least one contact arm, a first fixing portion and an extending arm extending laterally from the base, and a second fixing portion.

Abstract: A lamp system used in a light string system comprises a light assembly and a socket assembly. The light assembly comprises a light source, a base in communication with the light source, and a bypass activating system. The socket assembly comprises a socket adapted to receive the light assembly and a bypass mechanism having a first position and a second position. The bypass mechanism is in the first position when the light assembly is not seated in the socket assembly. When the bypass mechanism in the first position, current flows across the bypass mechanism. When the light assembly is inserted into the socket assembly, the bypass activating system of the light assembly moves the bypass mechanism into the second position, and current flows through the light source instead of the bypass mechanism.

Abstract: Morpholinos are widely used to block the activity of selected single-stranded genetic sequences. This invention comprises Morpholinos containing one or more integral photolinkers (Photo-Morpholinos) wherein the photolinkers are directly incorporated into the sequence of a Morpholino, where the photolinker has a size and structure which emulates the size and structure of a Morpholino subunit. This integrated photolinker design substantially simplifies and reduces cost of production relative to earlier photocleavable compositions. The invention also comprises use of these Photo-Morpholinos for modulating the expression of any selected gene transcript at any selected time and at any selected site simply by exposure to light. These Photo-Morpholinos afford a new use wherein a gene transcript is rendered inactive by contacting with a Photo-Morpholino—and then later exposure to light cleaves the Photo-Morpholino to inactive fragments—thereby reactivating that previously inactivated gene transcript.

Abstract: The invention relates to a double-layer card edge connector includes an electrical connection base and at least one latch member. The latch member has a first main arm and a second main arm arranged in an upper-lower and front-rear manner. A first slit exists between the first main arm and the second main arm. The first main arm includes a first downward pressing portion disposed at a free end of the first main arm and pressing a first electronic card, and a first clamping portion formed through extending from the second main arm and preventing the first electronic card from moving forward. The second main arm includes a second downward pressing portion and a second clamping portion disposed at a free end of the second main arm. The second downward pressing portion presses a second electronic card downward and prevents the second electronic card from moving forward.

Abstract: An apparatus and method to discriminate cardiac events by sensing atrial and ventricular depolarizations having associated refractory periods thereafter. A fast ventricular rate is detected in response to the sensed ventricular depolarizations. Responsive to detecting the fast ventricular rate, at least one stimulus pulse is delivered to atrial tissue within the associated refractory period of the ventricle but outside of an associated refractory period of the stimulated atrial tissue. A ventricular response to the atrial tissue stimulus pulse is determined, and the cardiac event is discriminated based on the ventricular response to the atrial tissue stimulus pulse.
