Abstract: A host device acting as a wireless hotspot can suffer poor network performance when many client devices are connected simultaneously, particularly devices with a poor connection speed. To improve network performance, the host device can identify a client device with the worst network connectivity based on wireless signal strength, a peer-to-peer (P2P) packet drop rate, and a P2P ping response time, and instruct the client device to scan the other client devices to identify the best candidate to serve as a new host device for the client device. The hotspot functionality can then be offloaded to the new host device with respect to the client device, thereby reducing the number of client devices connected directly to the main host device and improving the network performance of the client device.

Abstract: An example image forming device includes a wakeup source to detect an event for cancelling a power saving mode of the image forming device, a display, a processor, and a memory to store instructions executable by the processor. By executing the instructions, the processor is to display, through the display, a setting screen including a user interface to set an operation of the wakeup source, obtain information on a condition for cancelling the power saving mode based on setting information of the wakeup source received from the setting screen, and cancel the power saving mode in a case where a cancellation condition included in the information on the condition for cancelling the power saving mode is met in the power saving mode.

Abstract: According to examples, an apparatus may include a first feed element and a second feed element, in which a web is to be fed to the first feed element and from the first feed element to the second feed element. The apparatus may also include a controller that may determine whether the web exiting the second feed element is shifted from an intended position and based on a determination that the web is shifted from the intended position, cause the first feed element to be moved laterally a first distance and the second feed element to be moved laterally a second distance to compensate for the shift in the web exiting the second feed element.

Abstract: In some examples, an electronic device includes a lid section, abase section coupled to the lid section via a hinge section, the base section and the lid section having substantially parallel edges when in a closed position, and an antenna section including a first surface coupled to the lid section and a second surface coupled to the first surface via a pivot and to the base section. In response to a rotation of the hinge section, the pivot is to rotate between a first orientation when the base section and the lid section are in the closed position and a second orientation when the base section and the lid section are in an opened position.

Abstract: Examples herein involve amplification and detection of nucleic acids using a microfluidic reaction chamber. An example apparatus includes a reaction-chamber circuit to process a reagent and a biologic sample for amplification of nucleic acids. The apparatus further includes a plurality of capillaries to pass the reagent and the biologic sample through the microfluidic reaction chamber. A valve control system may selectively control each of a plurality of valves to cause the reagent and the biologic sample to selectively move through the microfluidic reaction chamber for the amplification of the nucleic acids according to a particular timing sequence. In various examples, a trapping region disposed in the microfluidic reaction chamber secures the nucleic acids in the microfluidic reaction chamber for amplification using the reaction-chamber circuit.
