The optical communication emitter includes: at least one light emitting unit, each light emitting unit comprising at least two light sources, each of the at least two light sources emitting light of a different color, wherein a unit optical communication time is divided into a number of time slots, which number correspond to the number of the light sources included in each light emitting unit, each time slot corresponds to the light sources that emit light of the same color, the light sources corresponding to different time slots are different, and each of the light sources can only emit light in the corresponding time slot.

Systems, methods, and apparatus for managing and controlling network-enabled movable barrier operators is provided. A method for managing network-enabled movable barrier operator includes receiving a user account identifier and a movable barrier operator identifier from a user device, providing an instruction to perform a specified action with a movable barrier operator associated with the movable barrier operator identifier to the user device, determining a registration condition is met upon detecting that the specified action has been performed, and, upon the registration condition being met, associating the movable barrier operator identifier with the user account identifier to allow a user account associated with the user account identifier to control the movable barrier operator over a network.

A key, a lock core and a lock, relating to a key, a lock core and a lock are provided. The key includes: a column body, a first end of the column body being provided with a light emitting component; a first cathode component disposed on the column body and connected to one end of the light emitting component to be mated with a second cathode component in the lock core; a first piezoelectric electrode disposed on the column body and connected to the other end of the light emitting component to be pressed against a second piezoelectric electrode in the lock core. When the first cathode component is mated with the second cathode component in the lock core, and the first piezoelectric electrode is pressed against the second piezoelectric electrode in the lock core, a piezoelectric current is generated, to cause the light emitting component to emit light.

A secured delivery system can include a doorbell device comprising a scanner, and a locking mechanism operatively connected to the scanner, a computer processor or a cloud server and a structure, such as a residence or lockbox. A key, which can be in the form of a bar code, can be generated and sent to delivery or service personnel needing access to the structure. The delivery or service personnel present the bar code to the scanner. Upon reading the bar code, the locking mechanism is unlocked thereby allowing access to the structure.

Systems, apparatuses, and methods are provided herein for securing merchandise. In one embodiment an apparatus for securing merchandise comprises a locking mechanism limiting access to one or more items, one or more optical sensors configured to detect a plurality of wavelengths and an intensity associated with each wavelength from at least one light beam emitted by an optical key, and a control device comprising a control circuit and a memory device. The control device being configured to store a lock code comprising a plurality of wavelength values and a plurality of intensity values each associated with a wavelength value on the memory device and determine whether to release the locking mechanism based on whether intensities of each of the plurality of wavelengths detected by the one or more optical sensors match the lock code.
