Abstract: The present invention relates to a pre-assembled unit having two tapered roller bearings, for a driven shaft designed to be replaced efficiently and to maintain optimal tightness as if it were factory assembled. The bearing comprises a rubber seal attached to the lateral face of the inner race of one of the tapered rollers, said face being opposite the smooth face of the other tapered roller. The necessary widening of the inner races requires a second invention, namely, a roller cage that allows the rollers to rock slightly in order to be assembled without causing damage or becoming damaged.

Abstract: A process for handling interleaved sequences using RNNs includes receiving data of a first transaction, retrieving a first state (e.g., a default or a saved RNN state for an entity associated with the first transaction), and determining a new second state and a prediction result using the first state and an input data based on the first transaction. The process includes updating the saved RNN state for the entity to be the second state. The process includes receiving data of a second transaction, where the second transaction is associated with the same entity as the first transaction. The process unloops an RNN associated with the saved RNN state including by: retrieving the second state, determining a new third state and a prediction result using the second state and an input data based the second transaction, and updating the saved RNN state for the entity to be the third state.

Abstract: A power unit powers a Long Range (LoRa) gateway at a communications facility. The power unit has one or more enclosures configured to install on a ground level of the communications facility. The one or more enclosures hold batteries and control circuitry. The batteries are configured to supply backup power. The control circuitry is connected to grid power, alternative power, and the backup power and powers the LoRa gateway with power-over-ethernet (PoE). The control circuity is configured to transition from the grid power to the backup power to power the LoRa gateway in response to an outage of the grid power. The control circuity can also transition to the alternative power, such as generator power or solar-generated power, to power the LoRa gateway. Finally, the control circuitry can charge the batteries using the grid power (if available) or using the alternative power (e.g., solar-generated power or other).

Abstract: A method including receiving, from a non-participant, a request to access a chat group at a voice call number, the chat group including multiple participants is provided. The method includes providing a list of the participants to the non-participant, so that the non-participant may select to talk to a first participant from the list of the participants, receiving a call, from the non-participant to the first participant, at the voice call number via a voice communication channel, and initiating a voice data transfer between the first participant and the non-participant through the voice communication channel. A system and a non-transitory, computer readable medium storing instructions to cause the system to execute the above method are also provided.

Abstract: A wireless power transmitting device transmits wireless power signals to a wireless power receiving device using a wireless power transmitting coil. The wireless power receiving device may transmit data packets to the wireless power transmitting device. The wireless power transmitting device may include a data receiver that is coupled to the wireless power transmitting coil and that receives the transmitted data packets. The data receiver may be configured to demodulate the received data packets. The data packets may include at least preamble bits, start bits, and data bits encoded as biphase half-bit signals in accordance with a predefined wireless power transfer protocol. During demodulation, the receiver may perform preamble detection, start bit detection, and data bit detection by comparing the input signals to corresponding reference patterns using a maximum likelihood sequence detection scheme. Phase recovery may be employed throughout to help provide immunity to phase change.
