Provided are a signal transmitting method and apparatus, a storage medium and an electronic apparatus for random-access signal transmissions. The method includes determining resources for a random-access signal in a region that comprises 36 subcarriers and six symbol groups. The six symbol groups are assigned indices 0, 1, 2, 3, 4, and 5, and a subcarrier index occupied by a symbol group is determined based on determining a first subcarrier index occupied by a neighboring symbol group, and determining the subcarrier index based on the first subcarrier index and an offset value. The method also includes transmitting the random-access signal using the determined resources.

In one aspect, a device includes at least one processor, a touch-enabled display accessible to the at least one processor, and storage accessible to the at least one processor. The storage includes instructions executable by the at least one processor to detect a hover of a body part of a user or other physical object above the touch-enabled display, where the hover does not include the physical object physically touching the touch-enabled display. The instructions are also executable to identify a graphical object underneath the hover and to cache data associated with the graphical object prior to the graphical object being selected based on the physical object physically touching the touch-enabled display.

A method, computer system, and a computer program product for dynamic internet of things (IoT) device grouping is provided. After an initial location of an IoT device is set, a current location of the IoT device is later determined. Thereafter, the determined current location is compared to the initial location. Responsive to determining that the current location does not match the initial location based on the comparing, a new IoT device group is assigned to the IoT device.

Routing data in a data confidence fabric. Data ingested into a data confidence fabric is routed to maximize confidence scores and to minimize the amount of missing confidence information. Routing is based on a configuration file and on pathing map information that allows nodes capable of applying the trust insertions set forth in the configuration file to be identified.

The method includes storing the local device data in the computer memory of the interface computer; transforming the local device data into a formatted data set; and transmitting the formatted data set to at least one remote monitoring computer.

A microcontroller configured to monitor the input voltage and load conditions, and continuously adjust the switching frequencies in order to optimize the efficiency and longevity of the power supply incorporated in a device. The microcontroller utilizes a combination of GaN switching elements with their efficient high frequency switching capabilities, together with the continuous monitoring of the load conditions, allowing the intelligent microcontroller to vary the switching frequency of the power conversion blocks as needed in order to maintain the highest efficiency of conversion. The microcontroller can be utilized to control a luminaire or other device into which the controller is preferably integrated. The microcontroller can utilize one or more environmental sensors configured for sensing internal environmental conditions and/or external environmental conditions. Preferably the microcontroller utilizes an energy storage device configured to power the microcontroller and associated sensors to allow the mesh network controls to continue functioning in the event of a power outage.
