A first mobile device including a connection terminal configured to electrically connect to a second mobile device, a variable impedance device connected to the connection terminal, the variable impedance device configured to vary an impedance, processing circuitry configured to determine a power line communication (PLC) mode between the first mobile device and the second mobile device to be one of a low-speed PLC mode or a high-speed PLC mode, and control the impedance of the variable impedance device according to the determined PLC mode, and a PLC modem configured to receive power from the second mobile device or communicate data with the second mobile device based on the determined PLC mode.

A case with an integrated or attached credential reader; when a user presents a valid credential (such as a biometric identity like a fingerprint, handprint, or face), the case is unlocked and the user can take items from the case. Sensors in the case such as cameras and weight sensors detect items taken by the user; these are automatically charged to the user or added to the user's shopping cart. The credential reader may be on a door handle so that as the user reaches for the handle the credential is automatically captured. The entire shopping experience may be quick and seamless since the user's credential may be captured automatically and the items the user takes may be accounted for automatically. Embodiments may have a door that opens automatically when the credential is accepted and closes and locks automatically when sensors detect that the user has retracted from the case.

Novel cable designs and methods for mass-manufacturing long, 100 Gbps cables suitable for large communication centers. One illustrative cable embodiment includes: at least eight pairs of electrical conductors connected between a first connector and a second connector, each of said electrical conductors being 30 AWG or smaller in cross-section and about 10 meters or longer in length, each of the first and second connectors being adapted to fit into an Ethernet port of a corresponding host device, each of the first and second connectors including a respective transceiver that performs clock and data recovery on the electrical input signal to extract and re-modulate the outbound data stream for transit via at least four of the pairs of electrical conductors as differential NRZ (non-return to zero) electrical transit signals each having a signaling rate of at least 25 GBd to convey a total of at least 100 GBd in each direction.

An automated store that calculates a confidence score for virtual shopping carts of shoppers, and selects carts for manual review based on these scores. Carts with low confidence scores may be more likely to contain errors, so prioritizing manual review of these carts is a cost-effective method of improving overall accuracy. A cart confidence score may be a function of factors such as confidence in the trajectory of the shopper generated by the store tracking system, confidence in the events (such as taking an item from a shelf) that affect the cart, and confidence that events are attributed to the correct shopper. Situations that make tracking, item identification, or attribution more complex may reduce confidence levels. For example, attribution confidence may be low when multiple shoppers are near an event, and item confidence may be low if the probabilistic classifier that identifies the item assigns nontrivial probabilities to multiple items.

The invention relates to a system and a method for continuing the transmission from radio transmitters to cable networks with the simultaneous increase of internet data transmission in the VHF range. According to the invention, the radio signals, destined for radio receivers connected to the cable network, and having an original frequency in the VHF range between 30 MHz and 280 MHz, in particular in the range of VHF-band II between 65.9 MHZ and 108 MHz or VHF-band III between 174 MHz and 230/240 MHz, are to be transferred into another free frequency range of the cable network by means of a frequency band transfer device (100), are to be transmitted to the cable network in this frequency range, and directly before the radio receiver, are to be transferred back into the original frequency or into another frequency that can be received by the radio device in the VHF range by means of a frequency band back-transfer device (200).
