The application describes generation of a data structure that enables comparison of any diamond to any other diamond. The data structure is generated via a sampling process and a computer system for acquisition of diamonds of a valid statistical sample having a predefined sample size. The process comprises tabulating the frequencies that diamonds of various grade combinations are available in an overall population of diamonds, then using a bidding process described herein to acquire a valid statistical sample of diamonds. The data for the sample of diamonds are then inputted into a Linear Programming and Mixed-Integer optimizer configured to sort all diamonds of the sample into sets with a median that is a minimal distance from the median on a scarcity basis, subject to various constraints, such as the number of diamonds in each set and a minimum total carat weight.

A system for controlling access to a secure room containing a plurality of safety deposit boxes, comprises a motion detector, a biometric sensor, and a plurality of contact sensors, wherein each of the safety deposit boxes is associated with at least two contact sensors. The system includes a processor that is configured to unlock the gate when a plurality of access conditions are satisfied, which may include: collecting via the biometric sensor a biometric sensor a biometric credential that matches a reference biometric credential in a user database; and determining the secure room is unoccupied based on at least a predetermined period of no motion detected by the at least one motion sensor. The processor may also be configured to generate a box-accessed event identifying one of the safety deposit boxes when all of the contact sensors associated with that safety deposit box are simultaneously opened.

A secure storage system for multi-user access having a plurality of lockable storage spaces, and a method for granting or denying access to the plurality of lockable storage spaces. A first subset of the lockable storage spaces is allocated to a first user and a second subset of the lockable storage spaces is allocated to a second user. A first access sequence of lockable storage spaces within the first subset is determined for the first user, and a second access sequence of lockable storage spaces within the second subset is determined for the second user in dependence on a likelihood of an access conflict with the first user. At least one delay period for at least one of the first access sequence and the second access sequence is determined if the likelihood of the access conflict remains above a predetermined threshold.

The present disclosure relates to a medium processing apparatus, including: a banknote device configured to process a banknote, including a banknote device door arranged at an opening of a safe box and being movable between an open position and a closed position; a banknote device lock configured to switch the banknote device door between a locked state and an unlocked state; a loose coin device configured to process a loose coin, including a loose coin device door arranged at an opening of a safe box and being movable between an open position and a closed position; a loose coin device lock configured to switch the loose coin device door between a locked state and an unlocked state, wherein the banknote device lock and the loose coin device lock perform a switching between the locked state and the unlocked state independently from each other.

In some examples, a controller includes a processing resource and a memory resource storing instructions to cause the processing resource to determine, via a radio frequency identification (RFID) reader in response to a storage bin of a kiosk being accessed, details regarding an item transiting the storage bin via an RFID tag associated with the item based on a received access request for the storage bin that includes an associated user identity, associate the details regarding the item with a user register associated with the user identity, and update an inventory of the storage bin based on the determined details regarding the item transiting the storage bin.

A method and apparatus for use in aiding provision of services requiring access through a physical key including the steps of providing a plurality of compartments with a digital lock for receiving the physical key and including the step of transmitting to a user providing the service with one or more of a digital keycode, time access key, and identity tag. The digital lock is activatable to open the identified compartment by receipt through a sensor of digital keycode and time access key and comparison of the time access key with the clock.
