Abstract: A cabinet lock for securing a door panel to a cabinet housing comprising a latching component, an electromechanical component, and a communications module. The latching component has a latch housing and latch member reciprocally translatable between locked and unlocked orientations to selectively secure the door panel to the cabinet housing. The electromechanical component includes an actuator operably coupled to a drive member that is coupled to the latch member whereby powering of the actuator translates the latch member to at least one of the unlocked or locked orientations. The communications module is configured for communication with a remote device of a municipal traffic control agency and/or a utilities worker. The communications module is configured to receive a control signal from the remote device for moving the latch member to the at least one of the unlocked orientation or the locked orientation.

Abstract: An electromechanical component for a locking mechanism is provided. The locking mechanism includes a latching component having a latch member reciprocally movable between a locked orientation and an unlocked orientation. The electromechanical component comprises a drive member configured to be coupled to the latch member, an actuator operably coupled to the drive member, a temperature sensor for sensing an ambient temperature associated with the locking mechanism; and a printed circuit board (PCB) in communication with the temperature sensor and the actuator. When the PCB receives a control signal to move the latch member between the locked orientation and the unlocked orientation, and the temperature sensor senses that the ambient temperature is below a predetermined threshold temperature, the PCB is configured to direct a pulsed current signal to the actuator to move the latch member between the locked orientation and the unlocked orientation.

Abstract: A cabinet lock secures a door panel to a cabinet frame and includes a latching component and an electromechanical component. The latching component has a latch member reciprocally translatable between a locked orientation to secure the door panel to the cabinet frame and an unlocked orientation to free the door panel from the cabinet frame. The electromechanical component includes an actuator and drive member. Powering the actuator causes the drive member to translate the latch member to the unlocked orientation. A drive member position sensor may emit a signal indicative of the position of the latch member. The electromechanical component may be retrofit-able to a latching component of a pre-existing mechanical cabinet lock.

Abstract: A method and system for writing a label (defined within a predetermined region of the sample 110), the label displaying a visible layout of light-modified regions in a predetermined spatial arrangement. The method comprises: modifying regions of a material within the label using light, wherein the modifying comprises using light of a first polarisation state to provide photo-induced optically active regions of a first type having a first optical activity state which is characteristic of having been formed by light of the first polarisation state, in order to encode covert information in the label using the locations of the first type of light-modified regions within the spatial arrangement of the label.

Abstract: A method for coordinating medical treatments and in-care patient tracking system is set forth wherein a patient peripheral enables determination of patient location data, patient identification data, and treatment data, by sensed spatiotemporal relationships of the patient peripheral within a designated area. Proximity of the patient peripheral with a practitioner peripheral enables automated association of treatment data to a patient record alongside practitioner identification data. Treatment data generated, such as collected samples and other data, effects automatic assignment of the patient identity to relevant data and materials. Inventory is trackable, and doses administered are reportable automatically to the patient record.
