A highly secure optical key access control system utilizing unique optical refraction properties of non-duplicatable transparent objects to secure premises or computer databases is disclosed. The said access control system includes an optical key containing an optical element with unique refraction properties and an access module comprising a light source, an image catching array and an electronic processor. The optical element of the optical key is inserted into the access module between the light source and the image catching array at the initial and then several following prearranged positions and a resulting set of unique refraction images appearing on the surface of the image catching array is processed with the electronic processor for comparison against preauthorized sets of refraction images to grant or deny access to the protected premises or protected computer databases.

It is provided a method for requesting remote unlocking of an electronic lock controlling access to a physical space. The method is performed in a user device and comprises steps of: sending a control message to an access controller, the control message comprising user authentication information, the control message causing the access controller to trigger the electronic lock to emit an alert signal; and sending an unlock message to the access controller comprising the user authentication information, in order to unlock the electronic lock.

A smart key box includes a key holding element, a housing, a power assembly, sensing units, an authentication module, and a control module. The housing is configured to contain the key holding element. The power assembly is disposed in the housing and configured to drive the key holding element to leave the housing or enter the housing along an access direction. The sensing units are disposed in the housing. When the key holding element leaves the housing or enters the housing, the key holding element is configured to trigger at least one of the sensing units. The authentication module is disposed at the housing. The control module is disposed in the housing and electrically connected with the power assembly, the sensing units, and the authentication module, and is configured to control the power assembly according to the at least one of the sensing units which is triggered.

The present invention relates to a shelf-stable cooking-aid for coating and flying a food product in one step for example in a heating pan, the cooking aid comprising 3-28 wt % oil, 20-60 wt % water, 2.3-5.5 wt % modified starch, 3-15 wt % salt, 0.5-30 wt % sugar and 0.5-30 wt % flavorings and wherein the cooking aid has a viscosity in the range of 8 to 60 Pa.Math.s at a shear rate of 1s.sup.−1 at 25° C., and the oil and water are in form of an emulsion. Further aspects of the invention are the method for making said cooking-aid as well as a method for coating and flying a food product in a heated pan or heated surface.

Methods and systems relating to administration of authentication information for electronic access control are disclosed. Authentication information is conveyed to an electronic locking device configured to restrict access to an entry point. In various embodiments, a smart device comprises a display screen for presenting a machine-readable optical code comprising encoded authentication information. An image sensor of the electronic locking device can decode the machine-readable optical code to obtain the authentication information. The electronic locking device is configured to permit access to the entry point in response to the image sensor detecting a machine-readable optical code corresponding to an access credential. A server device can provide authentication information to the smart device based on an access criterion. Conveying authentication information to the locking device may include rendering a webpage comprising the machine-readable optical code corresponding to the access credential.

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 for 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 determining and executing trusted user access. In one embodiment, a system for determining and executing trusted user access for smart locks at a retail shopping facility includes an access member, a smart lock securing the access member, a user interface device, and a control circuit coupled to the user interface device. The control circuit being configured to determine whether a user is a trusted user based on a determination that authentication data matches with stored authentication data within a threshold accuracy, and provide an optical key to the user interface device.

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.
