Abstract: A sleep device for newborns and infants that provides a separate but proximate sleep area near a caregiver or parent's bed and at the same level the caregiver is sleeping at for increased visibility of infant and easier access to the infant without the need for the parent to leave their own bed. The sleep device allows for more convenient access to the infant, better ability to soothe and comfort the infant thru close, yet safe contact, and easier access and egress to the adult bed. The sleep device can include a bumper that slopes downwardly in a direction from a rear bumper portion to a front bumper portion so that a rear side wall portion has a vertical height that is greater than a vertical height of a front side wall portion.

Abstract: Vibration devices are described that provide soothing movement or motion to a person, such as an infant or toddler, laying in a bed. The vibration devices are not part of, but are separately attachable to/removable from, the bed. The vibration devices utilize a control section that is outside the bed and a passive or active transmission element located underneath the mattress that transfers vibration motion to mattress the person is laying on. The devices described herein may also produce noise resulting from the generated movement that may be soothing to the person laying on the mattress.

Abstract: A toy apparatus includes a base having a first surface, a wall movably coupled to the base, and an actuation element located on the first surface of the base. The actuation element is rotatably coupled to the base, the actuation element being rotatable relative to the base in a first direction and in a second direction opposite the first direction. The actuation element includes a main body, and first and second extensions coupled to the main body. The first extension has first and second engageable surfaces, the actuation element rotating in the first direction when a force is applied to the first engageable surface and in the second direction when a force is applied to the second engageable surface. The second extension engages and moves the wall relative to the base when the actuation element rotates.

Abstract: A method for performing digital predistortion to a microwave radio transceiver in response to an increase/decrease of transmit power level is disclosed. If the new transmit power level is higher than the current transmit power level, a set of digital predistortion (DPD) coefficients is applied to the transceiver before the issuance of a transmit power level increase command to the transceiver. Otherwise, a transmit power level decrease command is issued to the transceiver before the application of the set of DPD coefficients to the transceiver. Determining the set of DPD coefficients for the transceiver involves two stages: (i) calibrating the transceiver at a room temperature under predefined conditions and generating a DPD lookup table including DPD coefficients at a plurality of predefined temperatures other than the room temperature and (ii) determining the set of DPD coefficients for a given set of operating conditions using entries in the DPD lookup table.

Abstract: A microwave radio receiver includes a first down-converter, a second down-converter, and a combined receiver signal level (RSL) and interference detector. The first down-converter is configured to convert a RF signal into a first IF signal. The second down-converter is configured to convert the first IF signal into a second IF signal. The combined RSL and interference detector is configured to determine one or more RSLs and generate an interference indicator based on the first IF signal from the first down-converter and a control signal from the second down-converter.

Abstract: A transceiver used in a radio unit for wireless communication, comprises: a circuitry board including a transmitter and a receiver; a first connector on a first side of the circuitry board, wherein the first connector is configured to be connected to an interface card; a second connector on a second side of the circuitry board, wherein the second side is opposite the first side and the second connector is configured to be connected to a digital card via a flexible circuit; and a pair of transmit port and receive port located on the second side of the circuitry board, wherein the transmit port is coupled to the transmitter and the receive port coupled to the receiver, respectively. When the transceiver is part of a split-mount radio unit (SRU), the first connector is connected to the interface card and the second connector is not in use. When the transceiver is part of an all-outdoor radio unit (AOU), the second connector is connected to the digital card and the first connector is not in use.

Abstract: A swaddling accessory attachable to a wearable blanket for use in swaddling an infant. The wearable blanket can be used with or without the swaddle to give the caregiver the option of using the wearable blanket without the swaddling accessory. The swaddling accessory and wearable blanket are equipped with fasteners that allow the swaddling accessory to be detachably secured to the wearable blanket in different positions relative to the blanket. The fasteners are positioned to prevent the swaddling accessory from being wrapped too high on the infant's body where it could potentially cover a portion of the mouth or nose. The infant's legs are left free to flex within the wearable blanket which helps to prevent hip dysplasia.

Abstract: A system to significantly improve the air quality in a personal breathing environment. The system includes a blower unit that produces a conditioned air flow, a delivery system that delivers air provided by the blower unit to a person's breathing zone, and a conduit that interconnects the blower unit and the delivery system for directing conditioned air from the blower unit to the delivery system. The delivery system is positioned so that it sends conditioned air around an individual's head and into the individual's personal breathing zone, thereby creating a zone of conditioned air around the individual's head.

Abstract: Commercial establishments that add MICR indicia to commercial instruments usually do so via laser printers that produce a high gain signal. Moreover, commercially printed documents that include MICR indicia can also result in a high gain signal. MICR indicia generated by laser printers are difficult to decode, using conventional DC biasing methods, because the laser-generated MICR high gain signals become clipped. Therefore, in order to decode these distorted signals, the present system processes both low and high gain signals to decode the raw MICR data.

Abstract: Airflow through a piece of furniture, such as a ventilated mattress of an infant sleep system, is conditioned. When applied to an infant sleep mattress, the conditioning improves the infant's sleep environment to promote the infant's health and/or enhance sleep. The conditioning can include the distribution of beneficial gases, vapor, heat, or other conditioning elements into the airflow. The conditioning can also include filtration of the airflow.
