Abstract: A three-dimensional (3D) printer and method of additive manufacture are disclosed. The method includes building a three-dimensional (3D) object via a 3D printing process. After the 3D printing process, the 3D object is contained within a cake comprising the 3D object and partially fused excess build material. The method further includes vibrating the cake to loosen the excess build material. The frequency of the vibration is swept across a predetermined range of frequencies over a predetermined sweep interval.

Abstract: In one example in accordance with the present disclosure, an additive manufacturing platform is described. The additive manufacturing platform includes a vibrating bed on which a volume of build material is to be disposed. The bed is to vibrate to remove excess build material and operates in at least two extraction modes during a build material extraction period. The additive manufacturing platform also includes a non-vibrating frame to support the vibrating bed.

Abstract: There is disclosed a method of cooling a bed of build material 12, 14 generated by additive manufacture. A container 10 containing a bed of build material may be provided, the bed having a hot region relative to ambient temperature. The container may be vibrated to fluidize unfused build material 12 in the container so as to cause convection of the unfused build material to cool the hot region. There is also disclosed a method of cooling a bed of build material 12, 14 including vibration when the temperature of a hot region in the bed of build material is higher than an unpacking threshold. There is also disclosed a cooling apparatus for cooling a bed of build material by vibration.

Abstract: An example three-dimensional printer includes a humidity source, a build material reservoir, a conduit between the humidity source and the build material reservoir, an air source to transfer air from the humidity source through the conduit towards the build material reservoir, and a valve assembly connected to the conduit to control a flow of the air in the conduit while the printer enters an inactive mode of operation. The air source is to remain in an active mode of operation. The air source is controlled to transmit the air in the conduit until the air in the conduit adjacent to the build material reservoir reaches a temperature and relative humidity threshold.

Abstract: This innovation provides a method and devices to manage IMAP Session timeout values by adding one or more proprietary parameters to the IMAP protocol. This provides the ability to modify the IMAP session timeout value after the IMAP session has been established and before the IMAP session expires. The mobile client may then choose to modify the timing of the IDLE message to the server based upon the newly received IMAP session timeout value.

Abstract: This provides a method and devices to manage the timeout value of data sessions between messaging clients and one or more messaging servers.

Abstract: This provides a method and devices to store the recipient status of all recipients of a message and makes the recipient status available from a network server to multiple client devices.

Abstract: An integrated motor and drive assembly includes a motor, a fan, and a drive unit. The motor is responsive to at least one drive signal. The fan is axially aligned with the motor and operable to generate a cooling flow. The drive unit is axially aligned with the fan and operable to generate the drive signal. The cooling flow traverses the motor and the drive unit.

Abstract: A process for the multi-layer repair coating of substrates, wherein a base coat layer of a water-based base coat coating composition is applied to a precoated substrate and a clear coat layer of a transparent clear coat coating composition is applied to the base coat layer thus obtained, characterized in that the base coat layer of the color- and/or special effect-imparting water-based base coat coating composition is applied in three successive spray passes, and each spray pass is executed such that uniform, adjacent and substantially non-overlapping coating strips are applied to the substrate surface to be coated.

Abstract: Detection of a fraudulent remote unit (113) in a communication system (100) occurs by external fraud detection equipment (103) located external to, and in proximity to a base site (101). External fraud detection equipment (103) communicates with base site (101) via an uplink communication signal (105) and utilizes fraud detection methods not utilized by internal fraud detection equipment (111) to identify the remote unit (113) as being fraudulent. Once the remote unit (113) is identified by the external fraud detection equipment (103) as being fraudulent, the external fraud detection equipment (103) places an origination order to the base site (101) and supplies identification information on the fraudulent remote unit (113). Infrastructure equipment (109) utilizes information supplied to it by the external fraud detection equipment (103) and disconnects the fraudulent remote unit (113).

Abstract: Notification of a feature-originated call is provided to a remote unit (103) by determining a feature indication message (312) based on a feature-originated call, and sending the remote unit (103) the feature indication message (538). The feature indication message is sent to the remote unit (103) via a base station (101) utilizing a downlink communication signal (116). In a preferred embodiment the feature indication message consists of a predetermined text message transmitted to the remote unit (103) and is displayed by the remote unit (103) on an alpha-numeric display.
