A safety helmet system includes a shell (10) and at least one brim (100, 200) that is detachably connected to the shell (10) via connectors (140', 140‴, 240) having insert portions (141, 241) that are secured by securing elements (150, 250) in insert apertures (40', 40", 40‴) of the shell (10). Two brims (100, 200) may be provided, one being a full brim (100) and the other a peak brim (200) forming a peak at the front of the shell (10), wherein the two brims (100, 200) are alternatively and interchangeably connectable to the shell (10). A peak brim (200) may be connectable by engaging the front edge (16') of the shell (10) to define a fulcrum (F) and then rotating about the fulcrum (F) to engage the insert portions (241) with the insert apertures (40") of the shell (10). Each insert aperture (40', 40", 40‴) may open inside the cavity (12) of the shell (10) so that the respective securing element (150, 250) is releasable from within the cavity (12).

A method comprises instructing, by a management application, a plurality of reader devices to perform a sequential inventory scan of an inventory environment, wherein the sequential inventory scan comprises each of the reader devices sequentially transmitting interrogation signals into an area of the inventory environment while all of the reader devices listen for and evaluate first response signals carrying first tag data received from a plurality of first radio frequency identification (RFID) tags positioned within a read of range of the reader devices; and instructing, by the application, at least two of the reader devices positioned within a predefined distance from each other to perform a concurrent inventory scan of the area of the inventory environment, wherein the concurrent inventory scan comprises the at least two of the reader devices concurrently transmitting power signals into the area of the inventory environment.

A radio frequency identity (RFID) tag reader. The reader comprises a radio transceiver; a non-transitory memory; a processor coupled to the radio transceiver and to the non-transitory memory; and an RFID tag reader application stored in the non-transitory memory. When executed by the processor, the application sends a message via the radio transceiver to a plurality of RFID tags indicating a first range of transmission time slots and indicating a second range of quiescent transmission time slots disposed within the range of transmission time slots, receives messages via the radio transceiver from the plurality of RFID tags during time slots that are outside the sub-range of quiescent transmission time slots, wherein the messages comprise information associated with items to which the plurality of RFID tags are affixed to, and transmits the information received from the plurality of RFID tags during the quiescent time slots.

A method of communicating between an Internet of Things (IoT) device manager and loT devices. The method comprises receiving information about radio conditions by an loT device radio relay from the loT devices; transmitting the information by the IoT device radio relay to an IoT service enabler platform; training a machine learning (ML) model by the loT service enabler platform based on the information about radio conditions; determining radio transmission adaptation rules by the IoT service enabler platform based on the trained ML model; sending the rules by the IoT service enabler platform to the IoT device radio relay; adapting a radio of the IoT device radio relay based on the rules and based on current radio conditions experienced by the loT devices; and, after adapting the radio of the IoT device relay, transmitting messages by the radio of the IoT device radio relay to the loT devices.

A method comprises determining, by an application, a current variance between a reference tag location of a reference tag and an active tag location of an active tag based on a response signal received from the active tag and an image depicting a light-emitting diode (LED) on the reference tag, comparing, by the application, the current variance of the reference tag location and the active tag location with an expected variance of the reference tag location and a prior active tag location, and performing, by the application, a corrective action when the current variance deviates from the expected variance beyond a threshold based on a rule.

A method of assisting to find an item inside a building. The method comprises monitoring a location of each of a plurality of radio frequency identity (RFID) tags by a wayfinding application executing on a computer system, wherein at least one of the RFID tags has a near field communication (NFC) capability; based on detecting that the plurality of RFID tags move in concert with each other, associating the plurality of RFID tags to a cart by the wayfinding application; receiving a request for directions to locate the item inside the building by the wayfinding application; looking up a location inside the building of the item by the wayfinding application; transmitting the directions by the wayfinding application to a user equipment (UE); and presenting on a display of the UE directions for the user to navigate to the location of the item.

Systems, methods, and devices can be utilized to schedule at least one Hybrid Automatic Repeat Request (HARQ) transmission and at least one HARQ feedback message in the same Physical Resource Block (PRB). A HARQ transmission can be scheduled in a mini-slot of the PRB. Accordingly, latencies associated with transmitting and receiving the PRB can be reduced, while the high reliability of HARQ can be retained. Implementations can be applied to 5G technologies such as Ultra Reliable Low Latency Communications (URLLCs) and enhanced Mobile BroadBand (eMBB), as well as other low-latency communications. A method can include determining a location of a device; selecting, based at least in part on the location of the device, a mini-slot size; scheduling, in one or more mini-slots having the mini-slot size in a PRB, a HARQ transmission; and transmitting, to the device, the HARQ transmission in the one or more mini-slots of the PRB.

A replacement head for a vacuum device includes a plastic tray, a filter and a pad. The plastic tray includes a dust chamber that has a sealing surface and at least one opening. The opening is provided to allow air, dust and debris to be drawn into the dust chamber during use. The sealing surface defines a sealing surface plane and the opening defines an opening place. The relative angle between the sealing surface plane and the opening plane is preferably between about -20 degrees and +150 degrees. The pad is attached to the lower side of the plastic tray and is in contact with the floor during cleaning. The filter is connected to the plastic tray such that the filter substantially covers a top opening in the dust chamber.

A cooking system including a housing having a hollow interior, a heating element associated with said housing, a support body for supporting the food within said hollow interior such that the food is positionable on a support surface of said support body, and a guard located between at least a portion of the support surface and said heating element. The guard is permissive of convective airflow between said hollow interior and said heating element, and is generally impermeable to projectile matter generated during a cooking operation.

Techniques for improving a vehicles access to GPS signals are discussed herein. An unmanned aerial vehicle (UAV) may be configured to communicate with the vehicle, such as a V2X capable vehicle, and provide GPS line of sight connection to a GPS satellite, thereby avoiding any blocking issues while maintaining accurate positioning of the vehicle on the ground. Short-range communications (e.g., Wi-Fi, PC5, unicast, etc.) may be used to provide the connectivity between the vehicle and the UAV. In some cases, a vehicle may drive into a designated area and the UAV and/or the vehicle may initiate connectivity with the other and start UAV assisted positioning services within the designated area.
