Abstract: Compositions and methods are provided for the cell-mediated targeted killing of diseased cells based on the presence of an intracellular antigen, rather than a surface-bound marker. The targeting cells are modified to express a cytotoxic protein that is delivered into a targeted cell, and after delivery is selectively activated by the presence of a cytoplasmic protein of interest. In one embodiment of the invention, the cytotoxic molecule is a Granzyme B (GrB) polypeptide. In the compositions of the invention, GrB is modified to render its cytotoxic enzymatic functions inactive, until the presence of an intracellular antigen unlocks the GrB molecule to enable enzymatic activities.

Abstract: A system and process for purifying and concentrating lithium using a sequential and cyclical process of charging and discharging electrodes to selectively push ions from cell to cell, repeatedly drawing lithium from a cell containing source brine naturally containing lithium into a cell containing recovery brine intended to continually increase in lithium concentration.

Abstract: A direction control device includes a housing, a wheel shaft supported by the housing, a wheel supported by the wheel shaft, a blade shaft supported by the housing, and a blade mounted on the blade shaft. The housing has a first side and a longitudinal axis. The wheel shaft has a wheel axis and is configured to extend beyond the first side outside the housing. The wheel has a rotational axis and is configured to rotate about the rotational axis. The blade shaft is configured to extend beyond the first side outside the housing.

Abstract: A ticketing machine on a wall includes an image projection device, a touch sensor, a wireless interface that is configured to communicate with a user's mobile device, and a processor. The processor is configured to project, using the projector, a graphical user interface of the ticketing machine on a surface and detect, using the touch sensor, a touch interaction of a user of the ticketing machine on the graphical user interface that is projected on the surface. The processor is further configured to determine a selection of an option of the user based on the detected touch interaction and provide, using the wireless interface, an entry product to a mobile device of the user based on the selected option.

Abstract: A method for conducting biometric transactions includes receiving an indication that a user's media is within a detection range of a transaction device. The indication includes an identifier of the media. A list is populated with identifiers of media that are within the detection range. The list includes the identifier of the user's media along with a subset of an overall population of identifiers of media that are each associated with a particular user and biometric identifier. A biometric identifier is received from the transaction device upon being received by the transaction device in an interaction with the user. The biometric identifier is compared to biometric identifiers of only users associated with identifiers on the list of media to identify the user and an account associated with the user. A transaction using the account associated with the identified user authorized and an authorization message is communicated to the transaction device.

Abstract: Systems and techniques are presented for processing a user through an entry location using a mobile device. User input is received indicating a request for access through the entry location. In response to receiving the user input, one or more images are captured and analyzed. A code is identified in the images based on the analysis and the code is translated to a code identifier. The code identifier uniquely identifies the code from several codes. A gate entry device is selected based on the code identifier from several gate entry devices. Further, a signal is transmitted to the gate entry device to grant access through the entry location.

Abstract: Systems and techniques are presented for identifying fare evasion at an access control to a paid area. Received signal strength (RSS) is determined for wireless signals communicated between two or more wireless transceivers and a fare media. A position of the fare media is determined based on the RSS and the position is added to a collection of positions. A position of an object is detected and the position of the object is compared with each position in the collection of positions. A determination is made that the position of the object is not proximate to any position in the collection of positions and an indicator light is generated on the floor proximate to the position of the object.
