Abstract: A testing apparatus for the detection of Legionella bacteria in a liquid sample includes a sample tray and a lid member. The sample tray defines a planar surface and a plurality of wells recessed relative to the planar surface and is formed from a permeable, transparent material that is non-toxic to Legionella bacteria. The lid member includes an adhesive layer configured to be sealed to the planar surface of the sample tray and formed from a first permeable material, a breathable film layer disposed directly about the adhesive layer and formed from a second, different permeable material, and a backing layer disposed directly about the breathable film layer.

Abstract: A strobe module can include a Fresnel lens that defines an external surface of the strobe module and a sidewall at least partially defining an internal volume and defining an external channel. A gasket can be disposed in the external channel. A substrate can be coupled to the sidewall to further define the internal volume and a light source can be disposed on the substrate in the internal volume.

Abstract: A detector for detecting the removal and/or insertion of a weapon out of and/or into a holster. The detector may transmit a message each time the weapon is removed from the holster. A recording system may receive the message and determine whether or not it will begin recording the data it captures. A detector may detect the change in a magnitude of an inductance and/or an impedance of a circuit to detect insertion and removal of the weapon into and out of the holster. The holster is configured to couple to the detector to position the detector to detect insertion and removal of the weapon. An adhesive tape may couple a detector to a holster.

Abstract: A game apparatus and more particularly a game apparatus utilizing a plurality of subject cards with corresponding decks of question and answer cards and including improved means for receiving, retaining and displaying the subject and question and answer cards.
