A robotic assistant comprises a plurality of sensors in a compact and unobtrusive form. One or more sensors may be emplaced upon a mast that may be selectively raised and lowered. The mast allows the robotic assistant to acquire images or other sensor data from a greater height, without substantially increasing the bulk of the robotic assistant. For ease of transport from one floor to another or from one building to another, the robotic assistant may deploy a handhold that a human may use to pick up and carry the robotic assistant. Floor characterization sensors may be used to determine characteristics of the floor such as if the floor is wet or dry. The robotic assistant may be used to provide a user with access to network services, to monitor a facility, provide telepresence services, and so forth.

An extensible mast device allows a payload to be supported at a controllable distance from a supporting device. A motor driving a flexible strip provides a force through the flexible strip to extend the mast. The extended strip may have a curved cross section that provides some rigidity. A set of telescoping sections may enclose the strip. One or more of the sections may be flexible. In the event of an impact between the extensible mast and an object, such as a user, the flexible section and the strip yield to the impact and collapse. The extensible mast may be easily reset by lifting it back to a vertical position, with the flexible strip reasserting the curved cross section and the flexible sections resuming substantially the same shape as before the impact. A robot may use the extensible mast to elevate cameras or other sensors to a higher vantage point.

Techniques for improving communications efficiency between pairs of communication nodes running within a computer system are described herein. Potential locations for placing a communication node are evaluated using one or more fitness values wherein the fitness value is based at least in part on one or more system metrics associated with placing a communication node in the potential location. If an improved location is found based on the fitness value, the communication node may be migrated to the new location, thus improving system efficiency.

Moving nodes in a distributed system

A first computer is selected for testing. Information sent from a second computer system to the first computer is intercepted. The information is modified to be noncompliant with a communication protocol, thereby producing noncompliant information. A determination is made whether the first computer device has failed to provide a particular response to receipt of the noncompliant information, and an operation is performed based at least in part on the determination.

Security verification by message interception and modification

Various examples are directed to providing thermal management to a computing device. The computing device may receive temperature state data describing a temperature state of the computing device. The temperature state may comprise a first temperature value at a first location at the computing device. The computing device may also receive use state data describing a first use state of the computing device. The first use state may comprise an initial operating condition of a first component of the computing device and an initial operating condition of a second component of the computing device. The computing device may determine that at least one temperature value at the computing device is out-of-range and select a second use state for the computing device. The second use state may comprise at least one of a new operating condition for the first component or a new operating condition of the second component.

System level thermal management

An electronic device includes an elongated tubular housing. One or more electronic components are coupled to a chassis disposed in a cavity of the tubular housing. A pair of elongated channels are positioned on opposite sides of the chassis and between the chassis and a sidewall of the tubular housing. The channels are tapered or wedge-shaped along their lengths. During assembly, one of the channels may be slid longitudinally along the other, causing the channels to expand laterally, due to their wedge shape, to secure the chassis in the tubular housing. The chassis and the pair of channels provide a thermally conductive path to dissipate heat. During use, heat generated by the electronic components is transmitted radially outward from the electronic components, through the chassis and the pair of channels, and through the tubular housing to the exterior of the portable electronic device.

Electronic device with efficient thermal dissipation

Data security is enhanced by injecting insecurity into communications between two computer systems to test one of the computer systems. The insecurity is injected by modifying the communications between the two computer systems by modifying or adding messages. A response from one of the computer systems is monitored to determine whether the computer system reacts to the modification in a secure manner or if mitigating actions need to be performed.

A stylus device including a first end or active end for writing and interacting with a touchscreen of a computing device, and a second end or passive end for using an erase function with the touchscreen of the computing device. This allows a user to write or interact with a computing device with one end of the stylus device and simply turn the stylus device over and erase without having to select an eraser function from a menu on the computing device. In this manner, the stylus device provides a more traditional method of writing and erasing, similar to that of traditional pencils.
