Abstract: During a password entry, a matrix is traversed to select a position. The matrix includes several levels, each level in the several levels including at least one position where data can be entered, where a second level in the matrix forms a sub-level of a first level, and where the second level is reachable only from a particular position in the first level. In response to an input, a mode of the selected position is changed such that the position becomes unchangeable and unselectable during a remainder of the password entry. The selected position is encoded in an auth-step. In response to an indication of an end of the password entry, an auth-code is transmitted. The auth-code includes a set of auth-steps, and the set of auth-steps includes the auth-step.

Abstract: A construction of a dynamic object password (DOP) is initiated by selecting an object from a set of objects in a step of the construction. A transformation is applied to the object to form a transformed object by altering a dynamic aspect of the object. A placement operation is performed on the transformed object relative to a field position of the DOP. As a part of the step, a triple is generated including an identifier of the selected object, an identifier of the transformation, and an identifier of the placement operation. The triple is transmitted as a part of transmitting an authorization code, the authorization code forming the DOP.

Abstract: Embodiments are described for logging in to a location-specific user account on a host system. An example method includes sending, by a user device, as part of a login request, an authentication image. The method further includes receiving an authentication response from the host system based on determining whether the login request is sent from an authorized login-location, which is based on a comparison of the authentication image with a reference image captured at the authorized login-location. The method further includes, in response to the authentication image matching the reference image within a predetermined threshold range, receiving access to the user account based on the authentication response.

Abstract: A wet cell battery, where a first cell in a wet-cell battery includes a set of anode electrodes and a set of cathode electrodes, and where electrically conductive debris accumulates on a surface inside the first cell to an expected height. An anode electrode in the set of anode electrodes has an anode end closest to the surface, and a cathode electrode in the set of cathode electrodes has a cathode end closest to the surface. A first gap distance between the anode end and the surface is different from a second gap distance between the cathode end and the surface. When the electrically conductive debris accumulates up to the expected height, the debris fails to make simultaneous electrical contact with the anode electrode and the cathode electrode due to the different gap distances.

Abstract: Embodiments of the invention relate to a multi-cell battery, with at least two cells electrically connected in a first parallel arrangement, which is connected in series to a second parallel arrangement of at least two additional cells. Each cell is locally connected to a sensor to sense and control current of each cell in parallel or parallel-series combination in the multi-cell battery. A control module is in communication with each sensor, and associated instructions electrically remove or disable a cell from the multi-cell battery determined to be defective based on measurements from the associated sensor. A configuration performs measurements and monitors a state of health of each cell in the multi-cell battery, the measurements including temperature, voltage and current sensing. Identifying one cell of the cells in the multi-cell battery as subject to a performance failure results in electrically switching the identified cell to an off position.
