Abstract: A system receives an order from one or more user client devices associated with an account of the system, and transmits a first notification to the one or more user client devices that an order is ready for pick up at a pickup location. The system receives location data from a particular user client device of the one or more user client devices. The system determines an outer geofence based in part on a running average time or wait time at the pickup location in a recent time period, a size of the order, or a historical wait time associated with the account. In response to receiving an indication from the particular user client device that a user associated with the particular user has entered the determined outer geofence, the system transmits a second notification to a runner client device.

Abstract: An online concierge system receives an order from a customer. The online concierge system transmits a notification to the customer's client device indicating that the order is ready for pick up and receives location data from the customer's client device as the customer travels to a pickup location. In response to the online concierge system receiving a first indication that the customer has entered an outer geofence, the online concierge system transmits a second notification to a runner's client device that the customer is in transit. In response to the online concierge system receiving a second indication that the customer has entered an inner geofence, the online concierge system starts a timer. When the online system receives a confirmation that the order has been picked up by the customer, it stops the timer and computes a wait time for pick up of the order.

Abstract: An interchangeable beam splitter holder includes a retainer which holds the beam splitter, and a front door and rear door which are both hingedly connected to the retainer. The doors are movable between a closed position, in which the doors substantially cover the beam splitter, and an open position, in which the doors are pivoted upwardly so that the beam splitter is exposed. The beam splitter holder also has three adjusting screws with ends which are adapted to abut against pivot points in the interferometer to thereby align the beam splitter. The beam splitter holder also has three spring plungers which abut against surfaces within the interferometer to push the ends of the adjusting screws against the three pivot points in the interferometer.
