Abstract: Techniques are described for debugging node devices. A node device may be connected to a host device for debugging purposes. A debugger, providing debug functionality, such as a debugging web application, may run on a remote server and be accessed via a web browser running at the host device, to debug the node device. Alternatively, the debugging web application may execute in the web browser running at the host device to debug the node device. In another alternative, the debugging web application may execute at a gateway device provided between the node device and the host device. In all cases the debugging web application is controlled via a debug user interface running at the web browser. Consequently, a user of the host device is not required to install a debugger at the host device in order to debug a node device.

Abstract: A method for managing a discontinuous call stack is disclosed to more efficiently use the memory of devices without a memory management unit.

Abstract: A technology is provided for sorting and accessing table data, comprising: receiving a request to retrieve data from a table having constant size keys and constant size data, the request specifying a key associated with data to be retrieved, the table having been sorted according to a sort order of transformed values derived by applying a consistent computational transform to each of the constant size keys; generating a first estimate of a table row for the specified key by transforming the key specified in the request into a transformed value using the consistent computational transform and applying a root-finding method to determine a table row; testing a table row key at the table row derived from the first estimate for a match with the specified key; and responsive to finding a matched table row in the testing, returning a data value from the matched table row for the specified key.

Abstract: Broadly speaking, the present techniques provide methods, apparatus and systems for monitoring operation of a device. More particularly, the present techniques provide methods for monitoring operation of a device based on a device firmware update that is associated with at least one power profile.

Abstract: Broadly speaking, the present techniques provide methods, apparatus and systems for monitoring operation of a device. More particularly, the present techniques provide methods for monitoring operation of a device by observing state transitions which occur during the running of a device process following a firmware update, and either comparing the observed state transitions to a state transition map generated within the device or comparing the observed state transitions to a state transition model in, or associated with, the firmware update.

Abstract: A method for detecting and responding to a configuration setting capable of causing undesired energy consumption in a configurable electronic device comprises measuring a power state of at least one connection point of the configurable electronic device to establish a measured power state value; comparing the measured power state value with a stored power state value for the connection point; and responsive to a discrepancy between the measured power state value and the stored power state value for the connection point where the discrepancy is capable of causing undesired energy consumption, emitting a condition signal.

Abstract: An apparatus and methods are provided to defending device against attacks. When it is determined that a device is under attack, a determination is made as to whether a layout of objects within said at least one resource at said device is protecting said device against said attack. The determination is then transferred to a remote server together with a layout of the resource at the device. When it is determined that the layout of objects within the at least one resource at the device is not protecting the device against the attack, then the layout of the at least one resource is changed. Either the remote server or the device may determine whether to change the layout in response to the attack.

Abstract: A method of authorizing an operation on a remote device with a cryptographic signature verification component, the remote device being operable in a communications network having human-readable messages with message signatures, comprising receiving at an arbitrator an authorization request to perform an operation requiring authorization on the remote device; retrieving from the request an operation identifier and plaintext data; sending a human-readable request with the identifier and the plaintext data to an authorizer; receiving a reply from an authorizer, the reply message comprising at least the plaintext data and a verifiable cryptographic signature identifying the authorizer derived from the request; and on receiving the reply, sending a request to perform the operation to the remote device with an authorization derived from at least the cryptographic signature, the cryptographic signature being suitable for verification by the cryptographic signature verification component on the remote device.

Abstract: Systems, mechanisms and processes are provided to allow law-enforcement officials, when encountering the potential use of prepaid payment cards in the furtherance of a crime or in relation to criminal activities, to (1) attempt to check the balances on such prepaid payment cards, including the ability to perform aggregate balance checks on a group of such prepaid cards, (2) attempt to freeze the funds on such prepaid payment cards, and/or (3) attempt to seize the funds on such prepaid payment cards.

Abstract: A machine implemented method of authenticating a communication channel between a first device and a second device by providing proof of proximity between both devices, the method comprising: generating, at the first device, an acoustic authentication signal to be received at the second device via a solid body acoustic coupling established between the first device and the second device thereby providing proof of proximity between both devices and so authenticating the communication channel between the first device and the second device.

Abstract: A set of polyhedral game pieces is suited for reinforcing certain mathematical operations. Each of the polyhedral game pieces includes a plurality of sides, each of which contains a number. The polyhedral game pieces are configured to reduce or eliminate occurrences of simpler math fact families when rolled. The game pieces are adaptable to numerous forms of game play to assist students in mastering more difficult math concepts.

Abstract: An electronic device is provided for managing assignment of peripheral devices in a virtualization environment. The electronic device can include a user interface configured to display one or more representations of virtual desktops. The virtual desktops are associated with corresponding virtual machines. The electronic devices can also include one or more processors configured to provide to the user interface to display one or more representations of the peripheral devices based on detection that the peripheral devices are communicatively coupled to a control virtual machine of the virtualization environment. The one or more processors can be further configured to detect one or more first inputs received with respect to the one or more representations of the virtual desktops and the one or more representations of the peripheral devices; and facilitate to establish one or more associations between the peripheral devices and the virtual machines.
