Abstract: A system and method use a physical unclonable function in a PUF circuit on an integrated circuit to generate a security key, and stabilize the security key by storage in a set of nonvolatile memory cells. The stabilized security key is moved from the set of nonvolatile memory cells to a cache memory, and utilized as stored in the cache memory in a security protocol. Also, data transfer from the PUF circuit to the set of nonvolatile memory cells can be disabled after using the PUF circuit to produce the security key, at a safe time, such as after the security key has been moved from the set of nonvolatile memory cells to the cache memory.

The sponsored story may describe an action of another user connected to the viewing user who has interacted with a social networking object. The one or more related posts may include content associated with the social networking object involved in the interaction described by the sponsored story. The sponsored story unit can optionally include an input element with which the viewing user can interact. The information received from the viewing user via the input element can be used to generate additional sponsored story units to the viewing user's friends.

Abstract: A viewing user is provided with an ordered group of advertising units when accessing content associated with a social networking system. Each of the advertising units can be related to a user activity, where the user activity is performed at least by the viewing user or a friend of the viewing user. The advertising units can be ordered using a sales funnel. In particular, the sales funnel may include a number of different positions. Each advertising unit can be assigned to a position in the sales funnel. Based on each advertising unit's position in the sales funnel, an ordering for the advertising units can be determined. The ordering can be used to place the advertising units on a web page requested by the viewing user.

Abstract: A social networking system may recommend a set of users to a viewing user for establishing new connections on the social networking system. Through a user interface, the viewing user may select filters based on characteristics and dimensions of user profile information. The recommended set of users may be ranked according to the selected filters by the number of mutual connections. Pre-populated filters may be selected and suggested based on information about the viewing user. Multiple filters may be selected by the viewing user, and filters may be based on any identifiable object in the social networking system, in one embodiment. The candidate recommended users may also be ranked based on predictions that the viewing user will initiate a request to connect with the candidate recommended users.

Abstract: A soft program method is provided for recovering memory cells of a memory array. In an embodiment, the method includes the following steps. Memory blocks of the memory array are soft programmed with first bias voltage. A selected memory unit within a selected memory block is then soft programmed with second bias voltage. Next, whether a judging criterion is met is determined. If not, the method is repeated from the step of soft programming with the second bias voltage; if so, whether the selected unit is a last memory unit is determined. If the selected unit is not the last memory unit, other memory unit is assigned as the selected memory unit and the method is repeated from the step of soft programming with the second bias voltage. When the selected unit is the last memory unit, the memory array is bit-by-bit soft programmed with a third bias voltage.

Abstract: The present invention is directed to a method of calibrating a light source. In one embodiment, a standard image sensor is used to capture emitted light of a standard and a to-be-calibrated light source in order to obtain a standard and a nonstandard image, respectively. A standard and a nonstandard luminance response are generated according to the standard and the nonstandard image, respectively. The to-be-calibrated light source is adjusted until the nonstandard luminance response is about equal to the standard luminance response. In another embodiment, the standard image sensor is used to capture emitted light of the standard and the to-be-calibrated light source. According to sampled outputs of the standard image sensor, a standard and a nonstandard chrominance response are respectively generated, which are used to compensate an image sensor under test.

Abstract: A gas diffusion layer with a micro protective layer is utilized in the electrochemical cells. The cell mainly includes end plates, current collectors, flow field plates, gas diffusion layers, catalyst layers, a proton exchange membrane and a circuit unit. When the cell functions as a fuel cell, hydrogen reacts with oxygen to generate electricity and water. Reversely, when the cell functions as a water electrolysis cell, water was decomposed electrolytically to produce hydrogen and oxygen gases. In this manner, the present invention particularly has the gas diffusion layer to be coated with a micro protective layer so as to prevent the gas diffusion layer from being corroded by active oxygen species generated within the oxygen electrode under the catalysis during water electrolysis operation.

Abstract: Network access providers implement interactive procedures and subscriber terminals employ embedded secure authentication structures and procedures to ensure that a satellite modem at the subscriber terminal accurately verifies the identity of a satellite modem terminal system at the location of the network access provider gateway facility during the satellite modem initialization process so that the satellite modem will only attempt to acquire satellite resource from the appropriate (authenticated and authorized) satellite modem termination system. In a virtual downstream channel environment, diverse downstream channel feeds are distinguished by authentication procedures. The present invention differs from standard theft of service prevention because theft of subscriber prevention is in a virtual channel environment, where subscriber terminals have access to a plurality of virtual channels by the nature of the signal.
