Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may monitor a set of time-frequency resources for one or more cell detection signals (CDS) associated with a pseudo-random sequence, where the pseudo-random sequence and the set of time-frequency resources are indicated by an output of a pseudo-random function (PRF) that is based on a timing parameter, a cell identifier (ID), and a shared key. Accordingly, the UE may communicate with a network entity via a cell associated with the cell ID based on receiving the one or more CDS. The UE may also exchange one or more messages with the network entity, and may perform a time calibration procedure based on the one or more messages and a delay threshold of the UE. The one or more messages may indicate an ID of the UE, a cryptographic number, a time interval, or a combination thereof.

Abstract: Catheters are presented herein having planar end effectors of various configurations, generally providing a two-sided and multi-layered platform for electrodes and sensors. In some examples, the end effector has a support frame (e.g. nitinol) between a pair of flexible circuits. The end effector can also include a polymer (e.g. silicone, LCP, etc.) between the flexible circuits and encapsulating the support frame. This platform facilitates positioning of electrodes on either side (including both sides) of the end effector in a variety of spacings and facilitates ultra-tight electrode spacing and/or a large area electrode. Sensors (ultrasound transducers, navigation coils, etc.) can be layered within the end effector between outer surfaces of the flexible circuits in a variety of configurations.

Abstract: An amplifier power attenuator utilizes an amplified audio feedback signal from an audio amplifier (which is driving a loudspeaker), along with a user-set impedance and a maximum voltage set-point reflective of the operational parameters of the loudspeaker, to attenuate an audio signal prior to amplification thereby preventing damage to the loudspeaker. The impedance of a variable impedance optocoupler is changed to adjust the attenuation of the audio signal to one of a plurality of predetermined attenuation levels responsive to an error between a voltage level of the feedback signal and the maximum voltage set-point. The error is reflected in a counter value having a linear or non-linear relationship with the error dependent upon a magnitude of the error; the counter value is assessed against a plurality of target values associated with respective ones of the predetermined attenuation levels to identify the attenuation to be applied to the audio signal.

Abstract: A multi-tenant system performs custom configuration of a tenant-specific chatbot to process and act upon natural language requests. The multi-tenant system configures the tenant-specific chatbots without requiring tenant-specific training. The multi-tenant system providing a user interface for configuring a tenant-specific set of permitted actions. The multi-tenant system determines a set of example phrases for each of the selected permitted actions. The multi-tenant system receives a natural language request from a user and identifies the action that the user wants to perform. The multi-tenant system uses a neural network to compare the natural language request with example phrases to identify an example phrase that matches the natural language request. The multi-tenant system performs the action corresponding to the matching example phrase.
