Abstract: Disclosed is a technique for passively monitoring the number of guests in a rental property. Mobile device broadcasts intended for connecting the device to a wireless network contain information about that device. This information includes unique identifiers such as MAC addresses. Detecting these broadcasts and filtering out those devices that are expected enables a property owner to have a semi-accurate number of guests within their property without actually being at the property, or visibly observing the guests in an obtrusive fashion. Guests are able to enjoy themselves in privacy and the property owner is able to monitor the safety of their property.

Abstract: Examples include determining content for displays based on bid requests. Some examples include transmitting a probing request to a display computing device and receiving a portfolio list from the display computing device. The portfolio list may include a first identifier for a first content stored on the display computing device. Examples may also include determining a user viewing history of the first content, and transmitting a bid request to the display computing device. The bid request may indicate the user viewing history of the first content.

Abstract: Mobile device detecting and engaging are described. A server can determine that a mobile device has connected with a wireless network at a physical location. The server can provide a captive portal of the wireless network to the mobile device to receive contact information for the mobile device. The server can then provide a message including information related to the physical location to the mobile device using the contact information.

Abstract: Disclosed herein is a technique to improve the processing of people counting systems. The technique involves ingesting raw people counting data into a time-series database sorted by point of origin and recorded by end visit time. That raw data is periodically summarized and then written to a relational database. Queries of the relational database for total visitor count over a period of time are modified by approximations of the raw data for particular classes of visitors. Examples of visitor classes include recurring visitors and pedestrians vs. people in cars.

Abstract: Disclosed herein is a technique to mask personally identifying information (PII) in a people counting system. A sensor that capable of identifying individual mobile devices, such as smart phones, counts people in a given area. Once identified, information that identifies given mobile devices is hashed. The hashed data is used with a filter to determine recurrence of individuals without actually storing any information specifically about those individuals. In order to determine the count of people externally from the sensor, the hashed data is analyzed for cardinality.

Abstract: Disclosed herein is a technique to improve the processing of people counting systems. The technique involves the use of a system that counts the local number of wireless/mobile devices via machine identifiers. When the counting device scrapes the machine identifier from a mobile device, the identifier is hashed using a one-way hash function. The hash code corresponds to a bit location on a bitmap. The location in the bitmap is checked. If the bit is already marked full, the mobile device has been previously detected, if the pixel location is empty, this is a new device. Thus, a single bit represents each machine identifier. The number of unique people in a monitored location is the number of full bits in the bitmap.

Abstract: Method for verifying a display of images on an electronic screen, comprising the following steps: displaying one image on the electronic screen; measuring one value of a display parameter during the display of the image; comparing the measured value of the display parameter with one reference value corresponding to one reference image; and if the measured value corresponds to the reference value, determining that the displayed image corresponds to the reference image. An electronic screen based on light-emitting diodes is used, and a power consumption of a portion of the electronic screen is used as the display parameter.
