The apparatus includes: a first electron emissive surface configured to receive an input particle and thereby emit one or more secondary electrons, a series of second and subsequent electron emissive surfaces configured to form an amplified electron signal from the one or more secondary electrons emitted by the first electron emissive surface, and one or more power supplies configured to apply bias voltage(s) to one or more of the emissive surfaces.

Abstract: Data is received that specifies at least one beacon associated with a first account and a first validity window specifying a time period during which the at least one beacon is to be associated with an additional account. Thereafter, a first entitlement is generated which, when registered by a second account, causes the at least one beacon to be associated with the second account until expiration of the first validity window. Prior to registration of the first entitlement and additionally outside the first validity window the at least one beacon is associated solely with the first account. After the registration of the first entitlement, the at least one beacon is caused to be associated with the second account during the first validity window. Other types of sharing parameters are also available such as sequencing, subsets of beacons, and the like.

Abstract: Methods, systems and devices for locating a wireless identity transmitter with a central server connected with one or more proximity broadcast receivers, such as stationary receivers or mobile devices operating as wireless receivers. The wireless identity transmitter may be a compact device configured to broadcast messages, such as through Bluetooth® advertisements, including an identification code. When within proximity, a proximity broadcast receiver may receive broadcast messages from the wireless identity transmitter and relay location information along with the wireless identity transmitter's identification code to a central server as sighting messages. The proximity broadcast receiver's own location may provide an approximate location for the wireless identity transmitter. The central server may process sighting messages, which may include signal strength information, to accurately locate the wireless identity transmitter.

Abstract: A server receives data from each of a plurality of code instances that characterize a location of an associated client device executing the corresponding code instance and comprising a unique instance identification (IID) that identifies such code instance. Thereafter, it can be determined, using a clustering model and based on the received data, which of the code instances are likely to be associated with each other. Next, each code instance can be grouped into one of a plurality of the groups based on the determination. Related apparatus, systems, techniques and articles are also described.
