Abstract: A wireless network connection management method includes at least one universal integrated circuit card (UICC) starting a search timer when utilizing a non-priority subscriber identity module (SIM) to establish a connection with a non-priority wireless network; the at least one UICC sending a search command to a wireless communication device in response to a first condition, wherein the first condition is that the search timer expires; a wireless communication device searching for and obtaining a current network status, and sending a reply message indicating the current network status to the at least one UICC; and in response to that the current network status indicates that a signal strength of a priority wireless network is greater than a specific signal strength, the at least one UICC informing and switching to the priority wireless network, and transmitting an update command to the wireless communication device.

Abstract: The present disclosure is drawn inkjet inks, which can include an aqueous ink vehicle and a pigment particle having a block copolymer attached to a surface of the pigment particle. The block copolymer can be linked to the surface through a nitrogen atom-containing coupling group bonded to the surface through the nitrogen atom. The block copolymer can include a steric stabilizing block formed by polymerizing a monomer having a sterically bulky group, and an ionic stabilizing block formed by polymerizing a monomer having an acidic group or a basic group.

Abstract: The present disclosure is drawn to polyurethane dispersions. In one example, a polyurethane dispersion can include a polyurethane with a polymeric ionic side chain and a polymeric non-ionic side chain. The polyurethane can be formed of polymerized monomers including a diisocyanate, a first polymeric diol, and a second polymeric diol. The first polymeric diol can include a first polymer chain replacing a hydrogen atom of a thiol group of a 1-thioglycerol molecule. The first polymer chain can include a block of a polymerized ionic group-containing vinyl monomer. The second polymeric diol can include a second polymer chain replacing a hydrogen atom of a thiol group of a 1-thioglycerol molecule. The second polymer chain can include a block of a polymerized non-ionic vinyl monomer, and the second polymer chain can be devoid of ionic groups.
