Abstract: Filtering device for filtering cerebrospinal fluid are disclosed. An example filtering device may include a filter housing having an inlet for receiving cerebrospinal fluid from a patient and an outlet for returning filtered cerebrospinal fluid to the patient. The filter housing may include a plurality of layers coupled together and defining a fluid pathway therein between the inlet and the outlet. A filtering section may be defined within the filter housing along the fluid pathway. The filtering section may include a widened region of the fluid pathway that is configured to slow the passage of fluid therethrough.

Abstract: A server establishes a secure session with a client device where a private key used in the handshake is stored in a different server. An encrypted connection is established between the first server and the second server. A message is received from the client device that initiates a procedure to establish the secure session between the client device and the first server. As part of this procedure, the first server transmits over the encrypted connection a request to the second server to use the private key. The first server receives, over the encrypted connection, a response to the request that includes a result of the use of the private key. The first server uses the result during the procedure to establish the secure session.

Abstract: The present disclosure relates to methods and systems for automatically providing a suggestion to delay sending a message that is being composed by a user to send to a chat participant using a chat feature of an application. The suggestion is sent in response to determining that one or more trigger conditions occurred. The suggestion includes a scheduled time to send the message. The methods and systems send the delayed message at the scheduled time.

Abstract: An aircraft can include a stacked propeller to generate lift during assent and descent. The stacked propeller includes a first propeller and a second propeller that co-rotate about an axis of rotation. In one embodiment, the blades are coupled to a rotor mast that contains an internal cavity. In one mode of operation, the first propeller and/or the second propeller can be stored in the internal cavity in order to reduce drag during flight. The aircraft can include one or more stacked propellers, such as a port propeller and a starboard propeller, which rotate in opposite directions during one or more modes of flight.

Abstract: The disclosure relates to improvements in methods for efficient editing of two or more endogenous tomato genes by insertion of one or more single stranded DNA donor molecules that are not homologous to the insertion sites in the tomato genome.

Abstract: A toy figurine comprising a surface portion in the form of a plurality of adjacent square portions. Each square portion has a side length of from about 1.5 mm to about 2.0 mm, a planar centre portion, and a perimeter portion surrounding the centre portion. The perimeter portion is a chamfer extending away and below the centre portion. The chamfer has a horizontal width from about 0.1 mm to about 0.3 mm extending horizontally away from the centre portion.

Abstract: A lacrosse training apparatus is disclosed and includes a head, a first rod, a second rod and a mass. Each of the rods has a length and is disposed in mechanical cooperation with the head. The mass is configured for movement with respect to the rods in response to a desired motion of the head. A length between a proximal portion of the rods is smaller than a length between a distal portion of the rods.

Abstract: A lacrosse training apparatus is disclosed and includes a head, a rod and a mass. The head includes a first dimension defining a first longitudinal axis and a second dimension. The rod includes a length and is disposed in mechanical cooperation with the head. The mass is disposed in mechanical cooperation with the rod. The mass is configured to move at least partially along the length of the rod in response to a desired motion of the head.
