Abstract: The present disclosure provides a method of measuring the quantity of analyte molecules. In some aspects, the method comprises compartmentalizing a sample with binding molecules conjugated to synthetic nucleic acid molecules such that the interaction of the binding molecules with the analyte molecules brings the nucleic acid molecules into proximity. Proximity triggers reactions that result in an optical signal, such as fluorescence, in analyte-containing compartments which can be counted to determine the quantity of analyte present.

Abstract: A method for securing a portable electronic device having a housing to a substantially immovable object utilizing a locking assembly having a security rod or spike formed with an anchoring end separated axially by a protruding end, a locking device with an internal locking mechanism and a cable permanently attached to the locking device at one end, includes several steps. The steps include securedly fixing the anchoring end of the security rod or spike to the portable electronic device upon or through the housing, attaching an other end of the cable to the substantially immovable object and inserting the protruding end of the security rod into an opening in the locking device to actuate the internal locking mechanism and lock the locking device to the captive security rod. Locking the security rod to the locking device concurrently locks the portable electronic device to which it is anchored to the substantially immovable object.

Abstract: A cup or glass is able to retain currency, either folded or unfolded, or a flat planar object, such as a standard-sized credit card or business card, in a slit located in the side of the cup or glass. Alternatively, two slits can be located in opposite sides of the upper rim of the cup or glass for permitting the two slits to jointly retain the credit card, business card or currency, or similar object, in the upper rim of the cup or glass. The cup or glass may have multiple slits for simultaneously retaining more than one credit card, more than one business card or several currency bills or, simultaneously, a combination thereof.

Abstract: A method for securing a portable electronic device having a housing to a substantially immovable object utilizing a locking assembly having a security rod or spike formed with an anchoring end separated axially by a protruding end, a locking device with an internal locking mechanism and a cable permanently attached to the locking device at one end, includes several steps. The steps include securedly fixing the anchoring end of the security rod or spike to the portable electronic device upon or through the housing, attaching an other end of the cable to the substantially immovable object and inserting the protruding end of the security rod into an opening in the locking device to actuate the internal locking mechanism and lock the locking device to the captive security rod. Locking the security rod to the locking device concurrently locks the portable electronic device to which it is anchored to the substantially immovable object.
